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)

ur pfp says it all :skull:
what do the squiggly lines mean?
123gjweq2 don't know chinese.
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.
there was blatant cheating in last DIV 1 + 2 , this blog explains it — https://codeforces.net/blog/entry/132571
update
damn he's really salty
so am i, i lost 155 rating :sob:
I physically felt the loss of my brain cells while reading this.
No way this man can even understand the problem statement
These guys are national embarrassments ngl.
you see,becoming a master is getting more and more difficult
i guess small account and cheater are some of the main problems
enhance anti-cheating system!!!
All the more satisfaction when you achieve master despite them cheaters. I too saw couple of cheaters in my room
why dont codeforces ban these account instead of skipping?
No I didn't, exposing cheaters to codeforces community is a fairly normal things we do.
Bro look at your comments! Yourself already tells me how you cheated, and then you claim that "I'm not a cheater"?
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.
Not even able to write properly, how did he read the questions lol...
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.
Make it public.
Updated:
he should have just at the very least not lie to try and defend himself, now everyone knows hes a cheater lol
Really sad to see.
Did he just started a new account ?
Who knows? I have no idea what is "Limet wer excced" he told in the message, my translater can't translate this.
I think it's the 2 messages per hour limit.
I believe he meant Limit was exceeded, u can write up to 5 messages per hour
Lmfaooooo. He just keeps on sending you messages. The audacity.
All cheaters are faggots.
as a faggot myself, we do not wish to be associated with cheaters
It's getting out of hands now. Only smart people like you can do something.we need something solid that stops the cheating.
I believe something similar happened with me. I checked the #1 guy in my room. He has been skipped once before Check this out :
274349019
274350830
Bro casually writes C to CPP code in under 1 minute:
271614633
271615456
If you look through his submissions, he first tries Python; if WA then uses C; then at last uses CPP.
aryanc403 used python for C yesterday. He has not used that language for a very long time. Isn’t it suspicious?
No, it isn't. It could be they were trying to avoid overflow or something with python. There's nothing sus about that.
Not sure about that but still I found it unusual.
did you even look at the bottom 2 submissions that have been made under a span of 2 minutes. No one can code up such a big solution in just 2 minutes.
Better float precision?
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?
Because he was not a poo like you.

bro has guts to write expert@codeforces in linkedin bio LOL....
ravikatharotiya392 is an absolute idiot, he has solved 3500 rated problems. Image a newbie or a pupil solving 3500 problem!!
He just copied the code of higher rated people, check this out: His: 275905651 The dude who actually solved: 269582810
No way. Lmfao.
Manish_Jangir another cheater who couldnt solve A in 50 mins then decided to copy from telegram till 3 questions lol
Not so sure about that. How about the probability that he was working on three problems at the same time?
Thanks for logical and unbiased thinking
yes it can be possible but looking at his solutions i dont think so
Bro if your basis of accusing someone of cheating is the time they took to solve some problems and or to couldn't solve some, then ig your basis are flowed. 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). And I simply and humbly discard your accusation. {Sorry for bad English thought :) }
it is not only about the time...by looking at your previous contests solution and that telegram group solutions.. both look very much common.. and the use of variable name such as f*ck to avoid plagiarism lol..At the end i would only say to get out of such groups and stop sh*tting on codeforces
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.
Cool idea. Build some sort of Codeforces Overwatch system like DotA 2 or CS:GO Overwatch.
A pupil and newbie just solved up to E. Cheaters are now reaching Div 1 level. We must be ever careful still.

MikeMirzayanov Ban plz cheaters
they're getting skipped!!
Disappointed in EduardoBrito
I, too, was in a room with cheaters. Better yet, I shared the stage with them.
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.
No evidence of proof doesn't means it didn't happened
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
MikeMirzayanov
I still feel like I'm a bit slow in solving them;(
vanshtomar001 also
like I am sorry but I didn't wanted to skip the contest, but I was as a guest in my friends house, so I wrote codes from my friends account, and then when I got home I submitted them from my account as well, I didn't knew if it was considered as a cheating(in fact it was bed form me because I started submitting 2hours later so contribution was big)
which problem impressed you
what do you mean?
I mean which problem I solved too fast
Bad cheaters
btw why don't you see their codes and hack their A code
Because I thought I could have solved D2, and I have no time to make hacks :(
Designed a user-friendly interface to enhance the efficiency and usability for restaurant staff. Utilized technologies such as **[List Relevant Technologies, e.g., JavaScript, Python, MySQL**] to deliver a robust and scalable solution.

This is from his linkedin bio. Dude didn't even hide it there.
klu-2100030642cser is now skipped.
They eventually fall down :) Cheaters can sustain for long
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 ???
[user:vanshtomar001][user:Vanshtomer001] i think is also in room but sadly he got skipped submissions. I THINK HE IS NOT ABLE TO CHANGE CODE THAT MUCH [user:vanshtomer001]
another cheater: mncuchiinhuttt
submission; 275821239
My rank in the contest is 5113.and after cf skip those cheaters’s code my rank come to 4626.That means there are 487 cheaters in top 5113 ranks.nearly 1 out of 10 persons is a cheater!
Actually, my rank was 1705, and after the cheaters were skipped, my rank comes to 1249. That is to say there are 456 cheaters in top 1705, way more than 1 out of 10 :(
this is what have been caught till now, the real number may be even larger. I think this is the most codeforces round ever till now in the number of cheaters, mainly because of placements and internships season in india (as mentioned above in the comments)
And those are just the ones who were caught.
Wow. My rank went up by 30. So atleast 30 in the top 550 got skipped. wtf.
Not all cheaters were banned for example MikeMirzayanov

My father says he would not hire people from India just based on their CF profile. They still have to go through the normal hiring process and solve coding problems to prove they are good enough.
Lmao I think that klu... whatever guy cheated again. This is funny and confusing at the same time. Are they really that dumb?
