Hi Community,
I would like to bring one point to your attention. This is regarding Psychotic_D, aka Dhruvil Kakadiya, the master-level cheater of India.
I am sure he cheats in almost every contest he gives.
He starts from D/E, usually when his friends get AC on those problems. Also, he knows nothing; he could not even solve B in the second last contest, which he gave. That's a fking IM for you.
He has been skipped twice earlier in rated contests due to cheating. His rating even reduced a good points indicating that he copied from someone. Now, this cheater has learnt to change the code to avoid plagiarism.
He earlier cheated from amenotiomoi and EndlessDreams, as per my investigation. I am sure he had the problems/solutions in yesterday's contest in advance before the contest. wuhudsm is a good friend of Dhruvil. They have created multiple contests together, it was quite unnatural for him to come and submit all the problems and achieve Rank 2. wuhudsm helped Dhruvil yesterday to achieve global round 2.
Also, this piece of shit is an IM and is still unable to grab an intern(He does development, so I am pretty sure he must have applied for SDE jobs, too), but he only does petty problem-setting jobs, which he grabs due to his IM title. His submissions and performance need to be thoroughly investigated.
He is currently running IICPC, which is led by Vivek Gupta, who posts on LinkedIn about cheating regularly. I am also against cheating, but one of your teammates is a great cheater. Both wuhudsm and Dhruvil must be investigated for this. Fking cheaters.
This also shows that wuhudsm is a failure as Problemsetter and allows his friends to cheat by LEAKING the problems in advance. I request to unrate this contest for Dhruvil and ban wuhudsm from creating problems. Both have ruined the integrity of the contest.
Also, the cheater Dhruvil has the guts to post on Linkedin, first learn to code perfectly man, you're an IM but still jobless. Atleast be true to yourself.
Psychotic_D reply to all my arguments, just providing an offer letter ss isn't the full reply and your innocence.
You have copied from amenotiomoi a lot of times.

I request everyone to make it post reach the admins of CF and let them take the final decision.
Those cheaters will try to report and downvote my blog, but I'll stay strong and report them. I have been observing them from a long time but yesterday it was too much.
A word to people newly clicked into this blog:
Please upvote/downvote the comments after reading the whole blog&comments. Many people are giving immediate upvotes when they find a message which seems logic. I mean Psychotic's comments.
alright, and why do I trust a person, whose post feels like personal hate, because it's targeting someone's insecurity.
Also, his skipped are in the past, what about yours, you have 3 contests skipped?
even I have 1 skipped, that's because in my early days, I wasn't aware about the true spirit of CP and solved collaboratively
It is what it is, man, and it does not target any insecurity. Just telling the truth. This is not my main ID, so why would I comment from my main one? This is one of my senior's IDs, who left CP and is now working full-time, idk about his records.
Why are you defending him so much, are you also the part of his group?
What you do is lynching. We don't do that in developed countries. All suspicions that arise must be addressed by the administration in a transparent official process. There's no need to make a personal spectacle out of it.
mate, I just pointed out the problems in your blog, To be honest, it felt like if you are someone from the same organization as him, and feel inferior.
No personal grudges, I am not commenting anything about the accusations, cause I got no view of my own.
I only pointed two things
Hating for not grabbing a job despite high rated, so according to you, High rated is directly equivalent to a intern or a job?
Pointing out skipped contests from past(2 years back), bring something recent, for proofs.
Now when i pointed you out for the same, you defending that it's someone else's account(which is also a point of suspicion, like what are you doing with his account?) and rather than talking logically, you trying to throw dirt on me, to shut me down?
I am not from his institute. Secondly, in India, a high rating(here, every rating) leads to Jobs, as it is assumed that these people are quite intelligent and work anywhere.
He is now smart enough to avoid plag; you can check ThinkAgain comments; he has attached the relevant proofs; check my blog with updated links; it consists of many proofs. It was my fault for targeting his unemployment, but I just wanted to make my argument a bit strong with it. The main fact is that he is a cheater.
just by looking at submissions of Psychotic_D and Endlessdreams in codeforces global round 26, there is definitely something going on here.
and as I type this Endlessdreams name has been replaced by amenotiomol in the original post.
Okay let's settle this.
And I always start from D/E because I want to be sure that if I can solve those or not, because I do not want the negative delta and I know I can do ABC fast enough.
Now, regarding the point where you mentioned I didn't solve problem B in the last contest. So, many didn't and you know the real reason beind it? lemme show you the reason, and the chat I attached is with tyr0Whiz.

And I secured 15th rank in the offline ICPC regional, now ICPC authors helped me? https://codedrills.io/contests/icpc-kanpur-2021-regional-round/scoreboard
I authored two rounds, and one is in the preparation stage, I stole problems?
I wasn't suspicious at first, but what is this?
Delete what? Did he send you an access link to a testing gym?
Yes, and deleted it in a microsecond, the thing was he misunderstood that I want to participate in the testing, but I asked him to delete it immediately.
I think being too honest is also a suspicious activity.
You can ask wuhudsm.
Also I request to compare my solutions with testers if you guys still suspicious.
FYI that does not qualify as proof, having access to problems in advance is already a sufficient unfair advantage. Whether you used said access or not should be verified by CF access logs if they still have them. Given the situation, I would ask somebody from the HQ to give a definitive public answer.
Sure, please I will be more happy than you for that.
I didn't even clicked the link, and for the honesty I attached everything crystal clear.
Thanks.
There's nothing crystal clear. Answer to my main reply at least below.
He might have the password of the Wuhudsm account to see the problems and solutions and then change it. He is a pro-level cheater and might have changed it to the max extent.
Also, can wuhudsm make the testing contest public? We would also like to see
It is perfectly fine and commonplace to invite your friends to test your round if that's what your last question is about. It indeed happens via sharing an invitation link with them.
This doesn't prove your innocence. That's just a weak excuse. If someone had access to the solutions or problems before the contest, they would take every measure to eliminate any suspicion of cheating.
bro u had many skipped solutions how it is possible if u don't do cheating
False flags can occur (see: https://codeforces.com/blog/entry/96313). But twice in a row is suspicious yes.
What are you trying to prove by providing wuhudsm's screenshot? He is also being accused of multiple accusations. He should also have the guts to speak.
Once again, asking wuhudsm does not prove or disprove anything. Deleting a discord message does not prevent access. A link can be copied to a clipboard, stored in the browser cache, etc. Only CF can tell us if you opened this gym link.
I presume by "being honest" you mean posting screenshots? I appreciate that you and wuhudsm are open to discussing this situation publicly, including your messaging history, but it does not qualify as proof. A clear conflict of interest must be settled through an official authority (CF administration), not via the witness statements.
I messaged KAN for the same.
Not everyone is a cheater like you, and Wuhudsm must have shared the problems with you . You are an excellent level cheater, and I have tracked you for the past year. Fortunately, I was able to track EndlessDreams and you. You provided a small part of your chat that doesn't specify that you were not asked/copied the problems from Wuhudsm before the contest.
You are not doing CP, and out of practice, you suddenly aced a "random" Div2 round, which was coincidentally your good friend's round—quite natural man.
Okay, why didn't you start from D/E yesterday? Were you sure that you could solve it? Both you and Wuhudsm are corrupt and don't deserve to be problem authors.
That's a lame excuse for not doing B, and I honestly don't know when you did that chat and if it is relevant to the same.
The above offer letter screenshot doesn't mention that it is yours. I can literally create like this in 100s. Neither your name nor the date is mentioned. There's no harm in even revealing your company if that's the case. Also, you were not able to grab any summer interns, which proves that you were not qualified enough.
EndlessDreams/amenotiomoi or any other is helping you to create problems. Idk but you are not the one who is smart enough. You are a damn cheater.
You tried to prove your innocence but you are not.
Also, wuhudsm sent you the testing link, but you asked him to delete it; you might have seen the problems.
Don't know anything about cheating part but not getting intern and being good at cf are quite common scenario these days, you would see many incapable people get summer intern through on campus placements thanks to random hiring of big mnc's
You probably should delete or blur the image, it contains your gmail address.
Ohh sorry. lemme put new one.
I think can't delete now.
Psychotic_D Reply to all the above questions, man; just providing an offer letter doesn't prove your innocence. This is the last thing someone wants to see. You can edit it.
You have cheated a lot, just agree the fact and all the best for your internship.
How ironic bro , how can you expect us to believe you when You yourself have 3 skipped contest and you are talking about someone other .
also his skipped contest are 2 years old already reallyy????
you did all that research just to find someone's 2 year old skipped contest
Though I do believe that it may have been unfair if he clicked the link and all but I cant just negate all the contest he has given in the past 2 years.
Even if it is truth , not you nor anyone in this community would agree that someone could reach IM with the help of cheating. I mean it is very high position in CP its not like every contest has his friends organizing it right??
and after this you are justifying yourself by saying that its not your real account and all ... though I am new in this community and not a friend of Psychotic_D nor do I have interest in your feud but this blog clearly tells your frustation towards him not in a very professional way that is ...
If your friend is an IGM or LGM, you can reach them by cheating. I have explained in the above comment regarding the skipped contests—Pranav16's reply.
asdfghjkljpEDH He is from CSE, and IM is a way too high position, even CMs and Masters have good chance of getting placed in top MNCs or HFT. There are multiple examples on LinkedIn: go and find, if an IM is unable to find an intern, then there's some issue with him.
hbarp They posted on LinkedIn against cheating, so wanted to show them the smartest Indian cheating, and also dhruvil is working with him(i am not sure tho).
I replied everyone in this comment, as I can do only 3 comments in 10 minutes
HFT only hires from IIT's afaik, I have seen CM's struggle to get test link because of college tier issue but I'M is too high of a rank to stay unplaced imo also.
Why are you just trying to spread hate? Being in a tier 3 college, and not getting the internship is an obvious thing. Getting placed in MNCs in on-campus placements via being in a tier 1 college is not comparable to not getting an internship in a tier 3 college.
and that all aside what do you mean "Master-level cheater of INDIA"
why are you trying to spread hate towards someone with there country as a tag. The world is very vast my bro and I believe there are cheaters in every part of this world , there are cheaters and non-cheaters only.
So please next time make sure not to mention their country just for justifying your point.
Idk about the post, but why are Priyash acraider and jaskaran tagged lol
Priyansh and the others are sharing on LinkedIn about this cheating on CF to raise awareness.
Seems like an obvious cheating to me as well. Such an over-performance on his friend's contest just can't be a coincidence. And those people are friends for sure:
But it seems to be well-prepared, so it will be hard to prove.
One of the things I have noticed in Psychotic_D's submissions is that he almost never uses spaces in his code. But any pre-written code he uses is formatted way better. Look at his solution for problem E, it contains more spaces than all solutions for A-D together. You may notice the small piece of code there that still doesn't contain proper spacing. And you know what? That's exactly the difference between his AC and TLE solutions. So, basically, he prepared a well-formatted TLE solution to make things look more realistic and knew in advance what to fix, but did it in his own code style. I would say, super fast for his level. In just two minutes he was able to submit solution, get TLE verdict, debug, fix, test (multi-testing in interactive problem for a second) and submit the modified solution.
Looks like an obvious cheating with pre-written code.
All this looks extremely suspicious and I would recommend ban wuhudsm from problem setting on Codeforces and skip all Psychotic_D's submissions in wuhudsm's round.
I would love to encourage people to upvote the_pain's post for better visibility.

Now, if you use vscode and press alt+shift+F, your code will be well formatted and since I was testing it locally I formatted for better readability.
I forgot to clear the graph, while returning, that caused me the issue so I cleared the graph.
And we are friends because we started TheForces together.
Why are your arguments just case-specific where doubts are there? You figured out what was causing TLE in just 2 mins. You intentionally added it to look genuine. Everything was so clear and perfect, as if it was pre-determined. You already had the problems/codes of yesterday's contest and were just waiting to submit them. You tried to be oversmart but ended up digging your own grave.
https://codeforces.com/blog/entry/131753?#comment-1173339 Reply these.
There's no point in cheating this much you have already achieved this much, and I assume amenotiomoi is also helping you at this moment with another ID since he has reached his max
And if you guys are happy by skipping my submissions, then it's fine.
Again don't blame wuhudsm, he did nothing wrong here.
I am not fan of rating or rank, if I am capable I will achieve that in near future again.
Thanks for your reasoning.
That doesn't answer my/pkhaustov's reasoning man. You do not have any argument to prove yourself innocent so you're playing victim card. Things do not work in this manner. You have to publically accept that you have cheated multiple times to reach this rating.
You are a cheater, and your ID must be banned. Also, wuhudsm has done many wrong things, so he should be debarred from writing public contests.
You are a fan of rating, or you wouldn't have flexed about this on LinkedIn and would not have cheated from day 1. Cheating from amenotiomoi simply shows you want to achieve good ratings and have fame. You are working with IICPC, which you do not belong to. But your CF tag has helped you.
You literally do not have the guts/arguments to reply on my comment. I asked and tagged you multiple times to reply on that, but you did not, showing your cowardness and cheating
You have posted on Linkedin, X, don't cry that you are not doing it for rating and fame, You just want to flex you cheating.
nice proof :clown:
did you even use a diffchecker? he just forgot to clear the graph.
Tourist had several bugs in D-F and he fixed those in 2 — 4 mins each time (though he had multiple ones on F). he must also be a cheater now.
About the formatting issue, he gave a very reasonable answer for it, and i ask you to actually go to his submissions and check other problems where he had to implement graph based algorithms, they are coded with very similiar styles (the actual code and not the formatting). Somebody else coded E for him, yet kept his style but formatting different? What a story!
I am also skeptical about such a nice performance on a friend's contest, doesnt mean I accuse him with such baseless and illogical proof. Expected better from a master
There's a difference between tourist and this clown Psychotic_D. The main argument was that he had the solutions/problems in advance, which led to his rank2. He has cheated and must be banned from participating, also wuhudsm must be stopped from preparing public contest.
where is your proof? coincidence is not a proof
should not he just skipped the contest if he had access to the contest problems gym before hand.
Don't even compare this experienced cheater to the strongest competitive programmer ever. But you actually confirmed my point: even for tourist, who sometimes solves three problems in 7 minutes, it takes 2+ minutes to get the verdict, debug, fix, resubmit.
I also had some recent issues with wrong multiple case handling and it took way longer for me to detect and fix it. Actually, just submitting and getting the verdict takes about a minute. But when you have something like TLE#2 on problem like that, your first reaction will be "Whaaat?! Where can this solution time out?" and after some time you need to find, fix, test manually (it's an interactive problem and you need to check at least two cases in one run) and submit it (which is not that easy with all this Cloudflare crap).
why do you need to check things? i normally first read my code before going to debug, its extremely possible to get this obvious error from just reading the code.
people resubmit in the same minute often realizing a silly mistake. I personally also have several examples (including just last contest G, use a diff checker to know my error)
kid, your logic is blowing my argument; I don't expect such baseless arguments from a GM. I have respect for you, don't let it ruin just because of defending a cheater.
Psychotic_D is a habitual cheater who cheats from amenotiomoi and endless dreams, and yesterday he had the solutions/problems.
He is a pro-level cheater and intentionally made TLE just to make it look genuine.
Not having proofs is not innocent, I am accusing him for cheating, but he only provided baseless points, SS and nothing else, where he should have replied, he did not.
STOP DEFENDING HIM.
where is your proof?? he made a very reasonable error that anyone can make, forgetting to clear a graph in between queries
Are you a donkey or what? Just see the comments which I have mentioned in the blog, he didn't reply to that, while he is replying to baseless comments, may be pkhaustiv's point is not much relevant, but it cannot be ignored by your irrelevant excuses.
how about you revealing your identity before calling someone a donkey/kid, why so scared
Why should I reveal my identity? I have put my points, and expecting Dhruvil to reply; some random kid coming to fight between two seniors should not be tolerated.
At least I don't. He is just saying anything to defend his friend.
You are only expressing your frustration and your statements are full of disrespectful words and personal attacks.
Just don't cross the line
prove it, which friends? EndlessDreams has been inactive for a long time now. can you send me specific contests where he copied from EndlessDreams instead of just accusing
He only had 6 minutes left in the contest after C (i reckon he was trying to solve F in the middle but then switched to C when he was running out of time to save some rank)
That is true, however doesnt mean he cheated now.
yes, pls make the investigation public, i want to see it too
These are the 4 points i found in your blog, each containing nothing of substance. The other guy atleast made some attempt at proofs, you did nothing.
I've told previously that his cheating will be hard to prove. And this is exactly why: he well-prepared it. Technically, people like you can always find examples that explain such a pattern. But if we consider all these factors together, it becomes really and really obvious. Let's be honest, despite it might be impossible to find a 100% robust proof, we both know this is not a coincidence.
if he was cheating, i sure hope he would do it better.
and no, im not even slightly convinced that its not a coincidence, infact i am less convinced than before this blog.
Come on, have you never had small bugs that you fix in under a minute and hate yourself for being so careless? It happens to me all the time.
Yeah, bro should have just skipped the round if the tasks were leaked to him. (not use this as a proof of innocence)
As Psychotic_D mentioned that he starts the contest after 30-40 mins to check if he can solve D and E problems but there is one problem with that , your solution timings directly coincidences with another one of your friend EndlessDreams which sends you the solutions and you change the plag on that problems and submit that and as you know it takes 30-40 mins to change ABCD problem which you claim to use the time for solving harder problems. Below are some of the screenshots of your past contest submissions.
As you can see the some contests are started from A when he either knew the questions before hand and someone was helping him and others were started an hour after that and started submitting solutions one after other and do i need to tell u he only submitted the problems which his friends sent. one other thing i noticed the unpredicibilty of his performance, one day he is an IM second day he just recieved a -100 delta. I never saw an IM who has that skills how can go from M to IM and back to CM in just 5-6 contests. Looks like something fishy is going on. Let us all make CF a healthy competitive platform by banning these so called programmers. Thank you
Your story seems ranodm.
https://codeforces.com/contests/with/satyam343 exaplain this, then.
300iq
Ha, this one is easy. I bought this account
Why are you diverting the attention from you to Satyam? Satyam is from a good institute and has quite a decent job in an HFT. and if in future, I get any doubt on Satyam, I will definitely dig and expose him.
We are not playing the blame game here. Explain your case here and reply to my arguments, or just keep quiet, you cheater. Go and stay with amenotiomoi and become his servant.
Just explain your case, you have cheated from endlessdreams and amenotiomoi multiple times, that's it.
You are always answer a part of many people's questions. Go and answer them all.
ok , forget about predictibilty , explain about your connections with other testers and your submission timings. we all just need to hear that , thats all I never saw such timings myself but hey im just jealous of your performance yesterday , isnt it, XD
what submission timings? do you have somebody who has very similiar submissions timings? would love to see that proof
how someone wants to do their contest is upto them, i know several people who start from D sometimes and sometimes from A
You are basically saying there is nothing fishy with this submissions timings. OK bro, I believe you, ig people will believe what they want to believe. Not going to comment more anymore. Cheers
there are 4 screenshots you sent
2 have ABCD solved very reasonably.
1 is sus on G yes, but i remember that problem. it was a single idea ac problem where if you get the idea you can solve in 10-15mins, so i dont find it unreasonable
another is just bricking? we all have our bad days?
There are plenty of suspicious things to point at, but discussing someone's rating fluctuation is absurd. Everyone goes through them, including me.
For another example person, here is an IOI silver who went from GM to CM then back: Everule
he is actually ioi non medal (barely missed out on bronze 200 cutoff was 205)
but he did solve the hardest problem (infact he got 100 + 0 + 0 + 0 + 0 + 100 sorted by difficulty of problems)
Oops I misremember. Thanks for correction.
pls enlighten us how, the friend gave 2 contests recently (counting from goodbye) and both of them even the number of problems solved doesnt match
Check the submissions around the time he became IM and please allow him to answer himself. I am sure there will a valid reason for that.
no, its not fair that 10 people will ask him questions and only he will be expected to answer
Why are you replying instead of him, are you his servant or what? Why is he not replying to any "main" accusation and "relevant points"? He just provided some baseless points and SS, and when people cross-questioned him, his ass was tattered, and he sent you to defend.
The rich(high rated) always exploit the poor. You are just defending a cheater which is definitely good for you.
You say what you want to say. You are a brainless donkey who is just defending your cheater friend with any kind logic, and I prefer not to argue 2nd-year juniors. Cheers!
lol, just imagine the level of hate towards someone, that you are abusing the people who are just giving valid points in his favour XD
A thorough investigation should be conducted against these cheaters. It appears this person has a large group that is mass downvoting a good post.
Yes even I feel he is copying yesterday vivek gupta shared a zoom meeting where he was showing how to generate problems on polygon .I think he has the access to the problemsetter account and got the question before the contest.
