Has the golden age of cheaters arrived in Codeforces?
By ShaoNianTongXue5307, 13 months ago, In English

As you can see, today's Div2 Rank1 syf2008 is a cheater, He and his friend Tx_Lcy cheats together. They have cheated at least twice between them.

For the first time, they received a cheating check message from Codeforces, as they wrote in their comments.

The second cheating occurred in Codeforces Round 857 (Div. 1) Problem C. They actually wrote the same code and made a lot of equivalent replacements, but due to FST, they were not caught by the system.

In this Div2, he submitted all the questions in an extremely abnormal order. Therefore, I reasonably suspect that they committed the crime in a team. (Upd: in comments)

I no longer want to care about any large-scale cheating incidents, but I want to say, if Rank1 in a contest can be obtained through a cheater, then the ranking of Codeforces becomes a joker.

rui_er At least do something, thx.

The code authors of his DE are different from ABC. syf2008 account is held by two people. I know there are precedents for banning team work acc.

Where is the proof for your words " they received a cheating check message from Codeforces, as they wrote in their comments " ? update-> here it is [user:syf2008] comment

I firmly believe you are correct accusing that user and speculating he cheated as he never secured a top 50 spot in div2 so how get rank 1 for such a tough contest? Something very fishy looks to have happened for him securing a div2 rank1 , maybe a potential problem leak given the extremely abnormal order, he submitted problems by.

Need to agree as they don’t even do plagiarism test too nowadays.. For the last Div 3 and the Educational Round (unrated, but still) there has been no plagiarism test till now..
