Cheaters of Educational Codeforces Round 99
By cheater_hunter, history, 4 years ago, In English

Hello everyone, I want to report two cheaters today.

@AchintyaK20 and @asinghkushrajj

Their submissions for almost all problems they solved in (Educational Codeforces Round 99) are the same the only difference is their templates and variables name. Also, there is very little difference in their submission time.

Their submissions for problem D

Their submissions for problem B

https://mirror.codeforces.com/contest/1455/submission/100019561

https://mirror.codeforces.com/contest/1455/submission/100017993

I request admin and community to catch such cheaters. It is very frustrating to see such kind of activity.

    Quick but stupid question, why do a lot of people post their new rank in Linkedin? Why Linkedin exactly? I thought that thing was made to look for jobs not for posting CP things?

One more cheater harshitkapoor.

His solutions also match with these two also the submission time is quite the same, but he has implemented it in Python. These three belong to the same college and also had made similar posts on Linkedin about this contest.

problem D 100020565 problem B 100019768

      The cf plagiarism checker is shit. When I say shit, the worst shit you can imagine. I have seen two people with exactly same code, just that one iterated vector with auto it: and another simply used a for loop, didn't get skipped.

While cheaters aren't getting punishments out there, my case with false cheating verdict is still left unresolved. My submission 99173403, 211's 99162733, confirmation from 221 himself. It is surprise that our 2 codes aren't even working the same, and people that managed that contest keep on ghosting my complaints. We need a system like Overwatch (similar in CSGO) where the community can cast vote on whether did someone cheat or is actually innocent.

Why should we even care? Do you think they will ever get anything cuz of this rating?
No interviewer will ever judge you on your rating (if the job is what concerns you).

I understand cheaters should be punished and they do affect ratings of others as well but it's not worth the efforts it require to detect this kind of plagiarism. Needless to say there will be 100s of solutions with same logic and many solutions with similar implementation.

MikeMirzayanov have betters things to do.

      Why did your mom even cared to give you birth?

      P.S:- You would understand when you face what overshadowed has faced already. My false cheating verdict is unresolved too for the past 5 months.

        What ? Do you even know in what context I was talking about? The other guy was saying everyone to mind their business and not to report cheating cases whereas this shouldn't be the case

        and

        Mind your language.

Hi everyone!

I am afraid MikeMirzayanov is not going to do anything about this. He just does not care about this things, in fact I reported cheaters multiple times and he ignored me since always.

You can check this blog I wrote some time ago, which had a lot a support from the community (regardless of being totally ignored): https://mirror.codeforces.com/blog/entry/75610

The funniest thing is that there I reported there were three people that cheat almost every contest (this was about 8 months ago!). AND NOW I AM SEEING THEY CHEATED ON THIS CONTEST, TOO!

Just take a look at problem B:

https://mirror.codeforces.com/contest/1455/submission/100002880 https://mirror.codeforces.com/contest/1455/submission/100005856

Or problem D:

https://mirror.codeforces.com/contest/1455/submission/100012818 https://mirror.codeforces.com/contest/1455/submission/100016190 https://mirror.codeforces.com/contest/1455/submission/100030502

Just a bit similar right? They cheat literally almost every contest and it seems no one is going to do anything ...

    (regardless of being totally ignored)

    So even though 2 of the examples there got solutions skipped, it was still "totally ignored"?

    And I don't think it is correct to say that Mike doesn't care about cheating at all. Here is a comment. Also the sheer number of people posting bogus appeals to "Rule about third party code is changing" should be a hint as to how many people get caught.

    The system may have many flaws but you are still being disrespectful here. A general tip: if you want X to listen to you don't start off by saying "X doesn't care about this".

      Sorry, but it is hard to believe Mike cares about it. That was just a comment he wrote, just some words .. but in reality I don't really see any changes.

      You can see it by yourself, just one example of it: https://mirror.codeforces.com/blog/entry/79271?#comment-649265. For example, we literally don't have any way to report cheaters, and a lot a people complained about that, and nothing changes..

      In this particular case, I reported those users in several ocations and they still cheat almost every contest... They are literally getting candidate masters by cheating, and I am reporting it, since months, and nothing changes... You really think Mike cares? I don't know him personally but from this situation I can't think he does ..

Not to blame Mike and his team for this. Cheaters always find a way. I don't have to mention what goes on in the telegram group these days. Everyone knows.
