Hello Codeforces! (this is how they write CF blog intros, right?)
I'm not really into catching cheaters in CF, I mostly prefer focusing solely on myself, but this participant (who ranked #1 in Iran btw) caught my eye
Her handle is MinaNiazizadeh
I don't know her personally, but Mina Niazizadeh sounds a lot like a Persian full name, so I'm assuming her name is Mina
Her first rated contest was Codeforces Round 1118 (Div.2), and here's some submission patterns:
WA1 spams on literally every problem
388783769 :
if __name__ == "__main__"is sus



Compilation errors on C:
388815219 : Python submitted as C++ (not direct evidence of cheating)
388828902 : Submitted with the three backticks LLMs use to format code blocks

I also saw a WA1 on C (388830966) after AC for some reason
She also participated in the recent ICPC challenge, but I saw no evidence of cheating there
So that's what I saw. MikeMirzayanov KAN please take a look at this matter









my first blog btw, sorry if it was boring lol
I think it would be good to post something a bit more productive. For example, an educational blog..Or maybe some resources that could help with competitive programming..
I think it would be good to not cheat like asterunee..
I don't cheat :)

Your rocket launch says otherwise :)

Almost all of the issues you pointed out do not necessarily mean the user is cheating.
Those comments don't give me the impression of typical AI-generated comments. Those usually are very verbose and frequent. I believe in more complex problems using comments is a good idea to remember what certain lines do in case you need to debug.
Could just be a style preference
Pretty self explanatory
As you said yourself, this has nothing to do with cheating. There's no need to add it to the list.
The only one that is for sure a red flag is the submission with the three backticks. It is used in MD to define a code block and it is the exact structures that ChatGPT and Gemini use. I just tried copying to clipboard a sample code generated by ChatGPT and the three backticks have been added to my clipboard too.
Still, this does not mean the user is cheating for sure but is surely something to keep in mind.
