I noticed several suspicious submissions from this account during recent contests.
Profile:

Evidence
• Submission 365891022 contains comments referencing animatronics, flash, and guard, along with a debug comment like // FIX:
https://codeforces.me/contest/2207/submission/365891022
• These terms are not present in the problem statement and appear to come from Five Nights at Freddy’s lore, suggesting possible LLM hallucination.
• Code across multiple submissions shows perfect / machine-like indentation and formatting typical of AI-generated solutions.
• Uses generic helper names such as solve, ok, req, lt along with debug comments like // FIX:, which commonly appear in AI-generated code.
• Rating jumped from Unrated → Candidate Master in ~2 months, which is highly unusual without prior competitive programming history.
• The user has also posted appeals regarding flagged or skipped submissions, which already raised concerns about originality.

• There is also evidence of disqualification during an in-person contest at NITK Surathkal.

Conclusion
The combination of:
• AI-style hallucinated comments
• machine-perfect formatting patterns
• suspicious rating growth
• previous flagged submissions
• and an in-person contest disqualification
raises serious concerns that this account may be using AI assistance during contests.
Please investigate this account.

check this out : Yet another suspicious account!! These cheaters need to be banned asap
ok but "animatronics" "flash* and "guard" are literally in the problem statement what are you yapping about
bro your own post is an AI hallucination
No, but it literally is. I put it in an AI text scanner and this post is 96% AI. There ain't no way we got AI posts in codeforces what the f**k
Current AI detectors are not accurate, and can not be used as evidence for AI usage. Although, it does seem AI assisted
the post sure feels like it.
The focus should be on the person/ handle using the AI and unfair means in the contests right, rather than focusing on the quality of the post???
Why to divert from the fact that the person has cheated, I did not have enough time to proof-read my post and write everything properly with exact details. Sorry about that.
The motive of the post is only bringing the cheater in the lime-light and hopefully getting him banned.
