What happens when an ordinary contest mistake becomes something you cannot get an explanation for?
I'm np254. My Codeforces account was disabled after Round 1121 (Contest 2264), and for the past four weeks I've been trying to understand why.
I know how this looks from the outside. An unusual variable name like Dr_Agos_pixels appears in my D solution. Two submissions appear close together, with the B solution accidentally submitted while A was selected. Someone sees these details and suspects AI or plagiarism.
But suspicion and evidence are not the same thing.
Here's what happened:
- A/B: I accidentally submitted my B solution with A selected, realized the mistake, and submitted it correctly under B.
- D: I chose the unusual variable name myself while experimenting with an approach that ultimately failed. It had no algorithmic purpose.
- Code similarity: My coding style and input-handling patterns are consistent with my previous submissions.
- AI and outside assistance: I did not use AI for contest problem-solving, copy code, or receive outside assistance.
I understand that saying these things does not, by itself, settle an investigation. That is exactly why I have repeatedly offered to explain my reasoning and implementation for every submitted problem.
What has been difficult is not simply losing access to my account. It is spending weeks trying to understand the reason, contacting the relevant people, and still having no substantive answer.
I'm not asking the community to declare me innocent. I'm asking for the opportunity to address the actual evidence.
If a particular submission, code similarity, or other signal triggered the disablement, could an administrator please clarify the concern or direct me to the appropriate review process?
I will answer specific questions and explain my code in detail. If there is something concrete I need to address, I want the chance to address it.
To anyone reading this: if you have experience with Codeforces account reviews, or know the appropriate channel for requesting one, I would appreciate your guidance.
