Hello Codeforces Administration,

I am following up on my account appeal for np254, disabled after Codeforces Round 1121 (Div. 2).

Over the past four weeks, I have submitted an explanation, contacted the relevant administrators, and made myself available to explain any of my submissions. I have not received a substantive response.

I understand that the administration may be handling many cases. Could you please confirm whether my appeal has reached the appropriate team, or advise me on the correct process for requesting a review?

I continue to deny using AI, copying code, or receiving outside assistance during the contest, and I am willing to cooperate with a review.

Thank you for your time.

I am not writing this post to ask the community to decide whether I am innocent.

I am asking a much simpler question:

What exactly triggered the disablement of np254?

My account was disabled after Round 1121 (Contest 2264). I have been trying to understand the reason, but I have not received an explanation.

There are two things that could potentially make my submissions look unusual:

1. The A → B submission incident I solved B, but accidentally submitted the B code while A was still selected. I realized it immediately, selected B, and submitted the same solution correctly.

2. Code similarity My contest code naturally resembles my older submissions because I use the same coding habits, formatting, input patterns, variable style, and implementation techniques.

That's it. I did not use AI, copy code, receive another contestant's solution, or get outside assistance during the contest.

So I'm not asking anyone to simply take my word for it.

If a particular submission, code similarity, or automated detection caused the disablement, please identify it. I am willing to explain the algorithm, reasoning, implementation, and even individual lines of any submission.

If I am wrong, I want to understand where I am wrong.

If this is a false positive, I want the opportunity to demonstrate that.

I am making a brief follow-up to my previous appeal regarding the disabling of my Codeforces account, np254, after Round 1121 (Contest 2264).

I have already contacted the relevant admins privately and explained the two points that I believe may have caused a false positive:

• The accidental submission of my B solution while A was still selected, followed immediately by the correct B submission.
• The possibility that similarities with my previous submissions were interpreted incorrectly by an automated checker.

I have also stated that I did not use AI or receive outside assistance during the contest, and I am willing to explain any of my solutions or reasoning in detail.

I understand that the Codeforces administration is extremely busy, and I am not asking for immediate action. I would simply appreciate a manual review or even a brief indication of what triggered the disablement, so that I can properly address the concern.

If there is another issue I have overlooked, I am completely willing to explain it.

Thank you for your time.

I am posting this on behalf of my friend np254, whose Codeforces account was recently disabled following Codeforces Round 1121 (Contest 2264). Since the account is disabled, they cannot publish this appeal themselves.

They have already contacted the relevant Codeforces administrators privately and sent a detailed appeal, but after several days their messages remain unread. They are therefore asking for a manual review of the account and Round 1121 submissions.

There are several points they would like the admins to consider:

1. The unusual A/B submission sequence

After their A solution was accepted, they used the browser's Back button to return to the previous Codeforces submission/editor page. Problem A was still selected. They then wrote their B solution directly in the Codeforces editor, but accidentally submitted it while A was still selected.

They noticed the mistake immediately, selected B correctly, and submitted the same B solution again, which was accepted.

Thus, the two submissions around the same time have a specific explanation: the B solution was written in the Codeforces editor, accidentally submitted while A was selected, and then submitted correctly under B. They are concerned that this sequence may look suspicious without the context.

2. Possible code-similarity concern

Their Round 1121 code follows the same coding conventions present in their older Codeforces submissions, including formatting, variable naming, loop structures, conditions, input-reading patterns, and overall program structure.

For example, the repeated do...while pattern used for input appears in their submissions from before Round 1121 as well.

They are completely willing for the admins to compare their Round 1121 submissions against their historical submissions, including Round 1120 and earlier.

3. AI-use concern

They state that they did not use AI assistance during the contest, receive solutions or help from another person, or share their solutions.

They solved A, B and C and attempted D, but their D solution was incorrect. They understand that this alone cannot prove authorship, but believe their complete contest performance should be considered together with their historical coding record.

They are not asking the community to determine whether the account should be restored.

They are simply asking the Codeforces administrators to manually review the case and identify what specifically triggered the account action.

np254 is willing to explain the approach, reasoning, implementation decisions, and even individual lines of every Round 1121 solution. They are also willing to provide any other evidence required.

If there is a concern other than the possibilities described above, they are equally willing to address it.

If an admin could please review the case or provide guidance on the appropriate appeal channel, it would be greatly appreciated.
