I was in a room of CHEATERS!
By cwz2024, history, 3 months ago, In English

In EPIC Institute of Technology Round August 2024 (Div. 1 + Div. 2), I failed to solve D2 and got -29, and look at the room I'm in! Pupil and specialist were extremely good at coding and they won ratings from naive CMs just like me!

ravikatharotiya392 failed system test on A, and this is what he submitted 275770575, and needless to say, 100% a cheater. And he had a skipped contest just a week ago.

klu-2100030642cser, converted his code to GO, perl, php with ChatGPT to escape plagiarism check. 275842762 275793939 And I'm pretty scared to see that he hasn't been caught even once in his 16 rated contests, he was a really clever cheater!!!

Just in one room two cheaters came and defeat me so much and I can't help imagining how many cheaters are there in the whole contest! Even problem E of Div1+2 can be solved by cheaters! Now cheaters can cheat their ways to Master! There has to be some measures to fight the cheaters (this is what we were asking for since months ago, but nothing happened). And is it possible to restrict some languages can be used in contests so cheaters have less languages to convert to and can be easier found by plagiarism checker? (e.g. C/C++, python/pypy, java, maybe kotlin?)

In the end, MikeMirzayanov please, at least skip these guys' contest (klu-2100030642cser can probably cheat the plagiarism checker again)

I strongly condemn such cheating behavior and I hope that Codeforces can enhance its anti-cheating system. Also,I hope that in the future, cheaters will become fewer and fewer.

cwz2024 here are some more potential cheaters guraj_97 ujjwal8409937761 gjfhj8528 electro-coder Qode_breaker Just see there submission of problems D1 and D2 they are just matching they have tried to add functions and even try to change whole flow of code to remove plagrism.
275846889 275825736 275821846 Just see this submission 275843826 how the person has tried to obstruct the plagrism but it is visible the code is copied. I urge MikeMirzayanov to skip there solutions from this contest and give them strict warning.

you did it in extreme level

No I didn't, exposing cheaters to codeforces community is a fairly normal things we do.

I am not a cheater

Bro look at your comments! Yourself already tells me how you cheated, and then you claim that "I'm not a cheater"?

There is some people might offending my whole country

Well, I'm sad to see that most of cheaters are from India. I have no idea what happened to India to make it become the most untrustable country in codeforces, but I don't care. However, if you know that your country is to be blamed for your behavior, then you should not do this at the very beginning.

    College placements are going to start very soon in India. Placement seasons starts from end September — mid October. These guys cheat to bloat their resume and secure a job. There is rampant cheating going on all coding platforms due to this. It deeply saddens me to see my countrymen do all this. My placement season too will start very soon. But I don't cheat in codeforces contensts. How is cheating in a practice contest going to help you clear an online assessment exam?

      But how are these companies not aware of the scale of cheating in Codeforces right now. They would at least check the applicant's profile to verify it's their account right? Otherwise everyone can claim they are a grandmaster.

        I think that companies are aware of this but they don't really care much. I don't think anyone will manually verify a candidate's cf profile. Last year, some people interened at Microsoft, Walmart without even creating a cf profile :D.

        One countermeasure is that people who pass their online assessment exams by ONLY cheating, miserably fail at their interviews. However, even this is not fool proof. Really sad times :'(

    What happened in India is that a bunch of youtube jokers advertised cp as something that can land you jobs or something like that (which is not true if you are under 2000 rated, because there are very few non development related jobs here). So a lot of people, especially those from bad colleges and with bad resumes, started farming rating on cf thinking this would land them a job somehow. Those youtubers who created this hype get to sell courses, while many students don't find this fun at all are wasting their time. Cheating is not taken seriously here because its very common to cheat in school and college exams, because of which many students get into the habit of cheating everywhere. These guys don't get that you will be required to prove your skills in an interview, where you won't get to cheat. Codeforces ratings are mostly useless in the context of job applications.

If you look through his submissions, he first tries Python; if WA then uses C; then at last uses CPP.

Wow ravikatharotiya392 how did you manage to write a C++ solution for problem C AND a Python solution for E just in 13 minutes? Problem C took me 9min already. You are so good. Is it because you code super fast, or you are smarter than others? It's a pity that you FSTed on problem A, which must have been unexpected. Otherwise you would be around rank 430. Can you teach me how to speedrun div1+2 CDE?

And to be honest I don't even care that much about these not the rating or anything. What's even the point when we all gonna di*e (sorry for this part).

        Bro tbh I don't even Know if such variable naming can pass the plagiarism check, it's jsut that you can't comeup with a good variable name under the pressure of contest going on when you already f*ck*d in the first question. And to add I'm not in any telegram group. Ig most of them ask for money and I just can't give that. Not to lie I tried earlier getting into a group, but they asked for money so I just never looked for that option.

Man some of these new Indians joining CF are spoiling the whole fun of CP and destroying the community by cheating. This is literally the most disrespectful thing for the people who are solving problems, putting efforts to be a good coder. It's such a shame. I really think most of the cheaters are from India because two years ago there weren't many Indians on CF now all of a sudden this crowd spoiled the platform. I mean I have solved 300+ problems(in my previous account) and I never even touched specialist, but I am ok with it cuz I wasn't very consistent. Remember "PROCESS TAKES TIME" Intuition is not something that will be improved in just few days or months! Cheaters are pure disgrace

So To all the cheaters out there F OFF.

Hey MikeMirzayanov, I suggest enabling Div. 1 users to report suspicious users for being cheaters which will be shown in the admin dashboard of Codeforces. Admins will review these suspicious users and take actions which in my opinion may be account deletion.

Codeforces could consider creating an official blog post after each contest, where participants can report links or share the code of suspected cheaters. This would help streamline the process and assist Codeforces in identifying and addressing unfair practices. Additionally, Codeforces should take action against cheating-related YouTube channels and Telegram groups to maintain the integrity of the platform.

This is a list of cheaters from the last Div4 round. All of them copied solutions and solved all problems in just a few minutes. Some of them even used ChatGPT.

Additionally, TonyWasHere was skipped in the last Round. If you look at his previous rounds (Like this contest that he solves 7 problems in 15 minutes), you'll notice something seems wrong.

After seeing this contest and the time difference between his submissions I think that this is a shared account

the first cheater-liked submission in D2 is from Way.To.Cp.01 at 00:42, at that time only 49 people solved this problem. I've read most of their code and didn't find any cheater-like code.

As those people are mainly GM,IGM,LGM, they may care about their rating so chances are they won't have time to modify their own code and give it to cheaters.

Check Way.To.Cp.01's previous submissions you can find that he has used the same template for a long time. Did he really solved problem D2 in 9 minutes and leak the code ???
