I noticed several suspicious submissions from this account during recent contests. https://codeforces.me/profile/Arjun_Dixit - 365891022 contains comments referencing animatronics, flash, and guard and an AI-generated fix comment. - 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 submissions shows perfect / machine-like indentation and formatting typical of AI-generated solutions. - Uses generic helper names such as
solve, ok, req, lt and 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. https://codeforces.me/comments/with/Arjun_Dixit - There is also evidence of disqualification during an in-person contest at NITK Surathkal. https://codeforces.me/group/NizPlqY552/contest/677887/standings/groupmates/true?hl=en-IN&mobile=false
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.
