I have been observing last few contest. Just look at these submissions.All of them had almost the same code with minor changes .Fortunately codeforces had detected the similarity in their code. But I guess these numbers are only the tip of the iceberg .God knows how many of them were not caught. Recently I saw a blog saying there is telegram channel where they discus solutions during contest and had given the link also .As soon as it was pointed out why the link was given and the blog could spread the link and increase the number of cheaters the blog was deleted. Kindly report any such channel and stop such practices .Moreover unlike codechef no action is taken on the person who was found guilty of copying .I would like to suggest to the following things:

  • Like codechef reduce the rating of those who are caught copying as penalty .

  • If same person is found copying multiple times ban him/her for next few contest.

  • There should be some way for a regular contestant to report such cases if he/she finds someone copying .

    Yes this blog had definitely manufactured new cheaters for both codechef and codeforces. I have met many people who believe that having a good rank in these websites will help them land a good job and this is why they tend to cheat. They need to understand that if they only want a good job then they should practice on sites like Hackerrank and Leetcode. Competitive Coding is more like a sport in which we participate because we love it and not for the reason of getting a good job and this is why people compete even after getting placed.

I think the id who do plagiarism, should be banned, at least for some time. Just by skipping codeforces cannot stop them, if codeforces start applying ban(for 1-2months or more) then this type of case can reduce otherwise i cannot see any solution :(

Like the open hacking phase we can also have a phase where we can report multiple codes which are possibly copied from same source and to make it effective the one who finds plagiarism gets bonus marks just like they get when they hack a solution.

      Do they have enough time for sharing idea during a short contest? Sharing code is much faster I guess. But the point is people are even giving away their solution for money.

        Any expert, specialist or even pupil can solve div2 D/E if the idea is given. And someone would not share his implementation in the fear of being caught right?

Unpopular opinion : These cheaters won't be able to solve beyond div2-C's so you just ignore them and work hard on your skills so that you won't be affected by them.

Because no matter how hard you try, cheating is gonna happen! So, just don't care, let the cheaters fuck themselves!

    I suppose that is one way of dealing with them but then also when its very obvious that the two codes are 100% same I believe they should be given some kind of penalty. Considering the fact that there is no penalty someone can use this as feature to never get negative rating change .Read this -->

No,I don't think that it's a good idea.B coz sometimes,it can happen that your code is similar to other one.U honestly didn't cheat,but it'll be a penalty.So I think that,codeforces should disable actions when a contest is running.(I am saying to MikeMirzayanov)If it's not possible,God will punish him/her.

I do believe there should be some way tagging them with a "cheating tag" that way they will be blacklisted from the college or community they belong (the tag will show on their ID thus showing their true skills). Just banning the ID doesn't make them stop but tagging the ID may at least make people know that they weren't legit after all.

          That is true. It is really hard to become Expert in just 1 month. I have done it in 6 months after a long path of learning and practicing. It is also a shame that he deleted his blog before a huge number of downvotes affect his blog. I'd suggest that after blog is deleted, if it had positive contribution, it would neutralize. But that won't happen for negatively affected contribution. For example, if a blog affected a person's contribution by -7, and that person deleted the blog, he would still have that -7. But, if another blog got +7 contribution and the owner of this blog deleted it, his contribution would return as it was as if he didn't write his blog. That is only my opinion. Downvote if you don't agree.

My view is to why even care about them. Almost all the cheaters are guys in the rating range 1100-1200 and they cheat and get to 1200-1300, thinking that is gonna fetch them a job. Let them stay in their bubble. Also there are no prizes for contests on code forces. So it's not like some undeserving guy is getting rewards by cheating. So the overall point is there is no way those idiots are affecting us. So why not just let them be.

It is hard to judge whether the participants are cheating or not. A number of the problems just need to calculate an answer in the program, such as A+B problem. Most of the program are in the same idea. In another hand,cheaters in codeforces has spoiled the contest a lot. So we must try to find a better way to detect cheaters and punish them severely.
