The reason I'm making this post is because the hack I used was very rudimentary, with $$$t = n = q = 1$$$. Shouldn't such a test be included in pretests/systests? Personally, if I had achieved rank 1 in contest but then gotten hacked by such a simple countercase, I would be distraught.
It's an alt of a well known cheater. LucaIlie
Guess who's back!

I used the same test to hack the solution of rank 24 ankitraj803120. (Name doesn't check out)
Submission: 349306725
Now I'm thinking we may be able to find more of these at the top.
UPD: Rank 54 youssefahmed3803 hacked — 349308161
interestingly both of them are cheaters what a sad day
Possibly the case, because ankitraj803120 hid their info.

A good way to mass-catch these guys is to sort codeforces submissions by memory usage. Go to any contest's "Status", then filter for AC submissions on the specific problem. And then, add "?order=BY_CONSUMED_MEMORY_ASC" to the URL. Then, check how much memory the GPT guys are using. Then roughly around there in the standings, you will often find loads more of them.
If it helps anyhow, the new winner is also most probably a fraud. Take a look at his submission to problem B (which gave WA2) just 5 minutes in the contest -- looks like the LLM has overfitted a bit :)
He also had a (longer-than-usual) solution to C submitted only 2 minutes after that one; achieving probably the fastest C (A) solution in both Div1 + Div2 in less than 2 minutes; and he even did it the 'slower-to-code' way, by simulating the process. In my opinion, 100% sus behaviour.
Plus, when he started climbing the rating ladder after a huge break, he completely changed the language he is working in.
can you dump him in my database please

Thanks
I have a question,how do you find the test that their submission dont bypass? Like you just make test generator and code to check his and your codes's output?

its the cf rate limit for viewing too many submissions
Oh okay but this happens to me a lot even though I haven’t opened that many personal submissions
