f8ck_cheaters's blog

By f8ck_cheaters, 4 years ago, In English

These 2 users from the same institute have cheated in the previous cf round.

Their solution for problem D :

User 1

User 2

Their solution for problem E1 :

User 1

User 2

It is clearly visible that second user has copied the solutions of first and also to avoid plagiarism, he has put useless if statements in the middle.

@MikeMirzayanov Please take some action against these kind of cheaters.

    Could have been better and more classy.

    If Plagiarism checking in CodeForces is done on source code without using a preprocessor, then it is really easy to cheat it.

    People here add tips in their code and god knows what, as comments so this won't trigger a red flag.

You should not make a new account to raise such a problem. Be brave to show your identity to these guys.

      Plot twist — all 3 had decided to give the contest together, but then the other 2 ditched him and hence the post

These same two users have cheated in the latest codeforces round #654 Check out their submission for problem B to E. Same logic just change of variable names and addition of useless if statements.

These type of users are only shame to the community and nothing else.

Check out this second user's template. ----Doesn't looks that he made it on its own;;;must have copied that too from someone else.

Even I am a low rated user,sometimes I am not able to come with A's solutions too,but that doesn't mean that I will ask from a second user for the solution just for the sake of rating change.

I request the community to ban these two users.

    First user is innocent till proven guilty. The second person might be trolling with a fake account and he has seen the first user's submission and copied it(Locking submission then seeing room's submissions). So for now, only the second person is guilty but the first is innocent.

      Chances are extremely rare when both are from the same college.

      What is the probability of a person being capable of solving a problem, solving it from a fake account to copy code of his batchmate and then submit it from his original account? I'd appreciate a rough estimate.

      Incase you tell me it's not zero, then the probability that two people end up writing the same code(without cheating)is also not zero and you can then call both of them innocent.

        Say the two people copying each other are A and B unless proven guilty obviously XD , and the person who wrote this blog is C. Now, what's the probability that C is actually user B just trying to drop off his other account(B) because he once wrote his crush's name on the code who later became his best friend's girlfriend. XD

I thought there were supposed to be a validator or something to check if a user cheats or not...

    Apparently it is quite easily fooled. If you make trivial modifications to the code, it seems like it doesn't catch it.

      Yes. It's pretty difficult to design a plagiarism checker as you don't want to accidentally catch those who didn't cheat. I feel like most of the cheater catching has been done by the community these days (as of now, humans are still more intelligent than robots on these matters).

        Judging by the sheer number of stupid comments that are left under "Rule for third-party code is changing" and assuming most cheaters don't even post there after being caught, I don't think so.

          Yes, but cheaters are getting smarter now. It is rarely the case nowadays that someone copy and pastes code from somewhere else directly. They usually change some stuff and then submit, making it much harder to be caught. I mean if you're going to cheat, chances are you won't make some stupid mistake.

I think there should be a report option . Where we can report and provide our complain.

These cheating cases are really disappointing for users like me who are even struggling for a specialist tag ( I am able to solve only first 2 or 3 problems in any live contest) because I personally believe that rating matters only when you have achieved it yourself rather than copying code for the sake of good looking profile.

    Don't be demoralised. I hope that one day you will be able to achieve the milestone you personally want to reach for yourself. Not for showing off, not for some job recruiting or other shit, but for yourself. I have seen people reaching a certain colour (Cyan, Blue, Purple, whatever one prefers) and not use that account anymore just to show it off. Don't fall for this trap. Stick to honest problem-solving. One day you will prosper. It takes time. And hard work.
