Hello Codeforces community!

In this blog, I'm questioning low_cortisol, is he a hidden LGM or a hidden LLM.

Firstly, his rating increase strangely. He got to Master in only 6 contests. In his first contest, he can only solve Div2A, and till now, he can do 5 out of 6 problems of an Educational Round.

Secondly, his AtCoder account, Lowcortisol have just performed suspiciously well (got top 13) in ABC454, outstanding LGMs like kotatsugame.

This lead me to the conclusion: (1) He's actually a hidden LGM (2) He's using Gemini Pro, or Grok, or any other models in his contest.

To be honest, his codes does look like it was written by a human. Oh, wait, what is the timing in this contest? He literally got an AC in E just two minutes after B? This is a thing that even cheaters like Thanmai_19 can't do.

So, if I wrongly accuse you of cheating, please leave a comment explaining what you did. low_cortisol.

Thank you.

Of course, the fastest way to become red is cheating. To be specific, use Gemini Pro. And, thanks to this method, I think Thanmai_19, jnccyyyq, ashgrove, nihaaleee, Terminator12, iammeteor, and phucngo2512010 will become a LGM soon.

1. Thanmai_19: He/she got AI comments in A and B, switched to Java in C and D.

2. jnccyyyq: Got TLE once in E, and then do it again with a totally different idea in just 7 minutes.

3. ashgrove, nihaaleee, harshxdsa: Many comments in their code.

4. Terminator12: Changed from Python 3 to C++ in just 3 minutes.

5. iammeteor: He/she got comments in E, and Vietnamese one in F.

6. phucngo2512010: His/her code for sure is made by an AI. Also, look at the time he got C and D correct...

Other suspects: undefined_Ryan, qwertyuiojhygtfdfg: I can't find any proof for these guys, I even looked at undefined_Ryan's past contest, but there are still no clue. Please tell me if I am missing something.

NOTE: THIS IS MY OWN OPINION, I CAN MAKE MISTAKES. ALSO, THE METHOD ABOVE IS JUST A JOKE, PLEASE DON'T CHEAT ;))

Hello Codeforces community!

After the previous Educational Codeforces Round 188 ended, I have noticed that there are so many cheaters who are maintaining their position at the top of the ranking. So, in this blog, I will list out some of them. Although my only method to expose cheaters is to look at their comments, I have found out quite a few of them.

Note: This is my own opinion, I can make mistakes.

1. The top 1 on the leaderboard, sonsimpmiku.

This one is quite obvious. He (or she?) got every problems accepted in 35 minutes, outstanding LGM like maspy, kotatsugame, etc.

2. Arthur_uncle

He got a big difference between his A — F submissions and G submission. Also, his submission for G has many comments

3. imakshat

Similar to Arthur_uncle, his F and G code got comments that look suspicious.

4. PKsilent

EVERY submissions of him have got comments in French.

5. ILoveNgocLinh

His comments aren't really suspicious, however, he changed his comments' language from English (in F) to Vietnamese (in G). Quite interesting, isn't it?

6. Last but not least, AshutoshSaugan.

This is the funniest case I've ever seen. In his submissions, none of them are suspicious. However, if you take a closer look, he submitted G TWICE, as he forgot to clear his AI's comments in the first one. This is the first one, and this is the second one.

Once again, this is my own point of view; I can make mistakes. If I missed anything important, please feel free to share your opinions

Thank you.
