**I noticed several suspicious submissions from this account during recent contests.**↵

↵
↵
**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. ↵
https://codeforces.me/comments/with/Arjun_Dixit↵
↵
• 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.↵
