I am writing this to just report some cheaters I found in the latest round (#804). aman_cod, bored_kid, amber_100, 1_2_3_4_5_9 are the ones that have cheated.
Have a look at the submissions of problem E from the contest Please look at the code in main void and compare as they have obscured their code to avoid plagiarism detection.
First one to submit : 162806135 Then the second guy submits it in python : 162804059 Then these two submitted the first code as it is but with alot of unnecessary code : 162802356, 162804537
To confirm you could also match their other submission from the contest and will find the similar pattern described above and all four of them solved the 4 questions i.e., [A,B,C,E].
Please MikeMirzayanov and geranazavr555 look into it and ban these guys.
Sorry for posting a blog which does not contribute anything to the community.
Auto comment: topic has been updated by To_catch_a_cheater (previous revision, new revision, compare).
I wrote this as these are not some low level cheater, all 4 of them are ranked in top 50 in the previous contest which hurts a lot of people's rank. So, they need to be banned.
but he run's a telegram group with 5600 members too!
Hey bro you have said I submitted it second but I submitted it even before the first guy. I have not obsfrucrated a single line in my code. I don't know how their code has similarity with me but it must be a coincidence and I have not cheated for sure.
Really dude! You trying to say these submissions are not copied. Look at these submissions for C and E (Being a unrated account can't add images in comment so adding links to the images)
Problem C Submissions side by side comparison
Problem E Submissions side by side comparison
It's too obvious my good sir. So, stop lying this ain't no coincidence. Clearly copied!
dear 1_2_3_4_5_9 Really impressive profile you have gotten now. I am blessed to see a legend like you. You have become my inspiration. Trust me from now on I also won't work harder but cheat harder like you sorry code harder like you but I will convert c++ code to Java(woot woot I am Groot). Please MikeMirzayanov please, It is an ardent request from me, please introduce a new badge named after my lord 1_2_3_4_5_9. I want to be the greatest cheater sorry coder ever.All hail Lord 1_2_3_4_5_9. Note: Cheaters are asshole and 1_2_3_4_5_9 is their god.Long live 1_2_3_4_5_9.
why your submissions in Hello 2022 have obfuscated code in them?
https://mirror.codeforces.com/contest/1621/submission/141560713 (C) https://mirror.codeforces.com/contest/1621/submission/141555135 (B) https://mirror.codeforces.com/contest/1621/submission/141501378.(A)
My dear friend(cheater), You first cheated in Codeforces Round #718 (Div. 1 + Div. 2) and last time in the div 3 contest(Codeforces Round #753 (Div. 3)). After that, your code got never skipped, also you started solving contests in python. Earlier This asshole used to copy code in c++ and when it got skipped, This idiot started a trick to fool anti-plague by changing c++ code to python. BOOM he is a pro awesome coder sorry cheater. He is a pro cheater(changing c++ code to python and variables).
Why do some Indians cheat all the time? You should learn from our dear Botswanaian Sparky_Master_WCH1226 ! 1_2_3_4_5_9, don't be another nitin_05!
Don't embarrass nitin_05 he was a noob cheater and got banned but this cheater 1_2_3_4_5_9 is a legend. Changing c++ code to python to escape the plague test is a legendary achievement. Even MikeMirzayanov would be very impressed with this new trick. Please MikeMirzayanov introduce a new badge of achievement Legendary GrandCheater for 1_2_3_4_5_9. After all his achievements should be well appreciated.
I think our dear 1_2_3_4_5_9 has never been tagged by so many people before. btw you are wrong, 1_2_3_4_5_9 forgot to use inline assembly:)
XD
lmao my ugly looking bro has been cheating from many years
Yeah exactly, 1_2_3_4_5_9 is a mass cheater that has two another alt accounts which are 14_15_16, 10_11_12
Also one person told me in dm that these people sell solutions during contests with high price, they're such a ..... people that have to banned from this community!
Amazing work, big fan
Noob coder but pro cheater
Along with banning cheaters, also add a cheater tag on their profile and don't allow them to change their profile info or delete account. This way they will get a lifetime cheater tag.
yes, To_catch_a_cheater did a proper research too before tagging.. good work
Yes, he is our messiah
I think it contributes a lot to the community. Just like referees contribute immensely in any sport, you did too. Thank You ヾ(＠⌒ー⌒＠)ノ
Ban them, plz.
Support To_catch_a_cheater!!!
Codeforces should be a fair platform for us to code and contest.
Never banned them, this will only lead to new account poping up every day. Just give them lifetime cheater batch. And take all rights to change their social info in any way. This is better than banning them i guess.
Yes I agree with u.
Also, I think Codeforces can develop an anti-cheating system. It just need to delete useless codes (like comments) and compare the codes to judge if the code should be skipped.
Many other coding and contesting websites have this system and I think Codeforces can develop one too.
If there is something wrong with my comment, plz, point it out for ne, thx.
Great job bro, it contributes much!
The rating changes looks so similar for all of them (except one) lmao
As everybody can see They all solved ABCE. These stupid idiots sell solutions on Telegram and they think they are smart. here I am attaching ss where you can see ABCE gang leader boasting of having solved ABCE. I urge everybody to respect new CM(cheater) 1_2_3_4_5_9. He has completely revolutionized the way of coding(cheating). He has invented a new trick for fooling cf anti-plague test. I would ask fellow coders to nominate him. for nobel prize of coding(cheating). I am sure he will take cp community to a new level. Good luck 1_2_3_4_5_9 I hope you will code(cheat) hard and become a grandmaster.
This guy did some serious preparation for this post. Reaching CM level by cheating is something very bad. I have seen a lot of people struggling to reach even pupil, yet they rely on their hardwork. These cheaters should really get banned for doing this type of thing.
1_2_3_4_5_9 — You dirty stinking cheater. I hope you never participate again.
To_catch_a_cheater, love your YouTube content man, also great work! 1_2_3_4_5_9 is totally the coolest dude of all time, he's such an idol i can't thank you enough for letting me know of their amazingly awesome existence /s
i like how you were really well-researched and not just accusing people without proof like many people do. The fact that you went through their submissions and shared the side-by-side code comparisons is super cool, nice valid claims. Good job exposing these A-holes.
You and hunter_of_alts really live up to your names!
Wow. Legendary Grand Cheaters :O
No this do contribute because these cheaters are taking the rights of the others and you are the one who is standing for their right
Why are these cheaters still have their as accepted?
MikeMirzayanov why aren't you doing the plag check and at least skipping these cheaters?
it's 3 days now, skip their solutions or ban them. Becoming a CM by cheating and solving problems is unacceptable and unfair to those who solve on their own.
MikeMirzayanov skip their solutions and ban them.
Maybe the plagiarism checks of different languages are not easy. But these cheaters should be banned right now.
some lines of codes can be similar, doesn't mean I cheated.Really????
your submission :- 168579150
other cheater's submission :- 168571116 168580011 168586310
It is incredibly shameful that despite reporting MikeMirzayanov about the cheater gang in the last contest and the following submissions with obvious Obfuscated Code wrt to the first submission and the subsequent submissions by these cheaters who changed the code to python to submit python submission. Until now, none of their solutions has been skipped; in fact, their ratings have increased. Great job MikeMirzayanov in harbouring cheaters on the platform. It won't be long before we see cheaters in yellow or even red.

This guy has again cheated by submitting 5 solutions in 2 minutes, and it's visible that he knows nothing. MikeMirzayanov please look into it and ban him.
Wonderful. The cheat art, 1_2_3_4_5_9 today beat grandmasters. What a powerful and fast python obfuscator.
ㅤㅤㅤㅤㅤ ㅤ
currently I don't have time but when I become high rated , I will make a blog which will be a list of people who cheated atleast once in codeforces , and that list will be updated day by day through people's comments exposing potential cheaters and I will look whether they are actual cheaters and if found evidence I will update the list putting their names
he didn't cheat and do not do this!!! Shame on this blog for posting normal people as cheaters!!! :(
MikeMirzayanov It has been 2 years of this blog still no action? The cheater mentioned in the blog has made several telegram grps and leaking solutions still no action? Why...He is just ruining the platform
