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.
