AtCoder Account Issues

I recently noticed that my AtCoder account may have been banned by accident or deleted, as the profile link now redirects to a 404 Page. I had a last rating of 1916, after giving the ABC 467.

At this point, I’m unsure if the account can be recovered or if I may need to start anew under a different persona. I have raised a support ticket, so let's see if I am able to recover the account. Hopefully it does get recovered.

Update 10/8/2026

I have received an email stating that I had violated the Terms of Service. I have mailed back to request details of the terms broken, so I don't make that mistake again. Let us see what happens. I hope to find a resolution soon, as I’ve invested a lot of time and effort into building my profile on AtCoder. 

Update 18/8/2026

Seems like the account is gone. They replied back to me stating that:
Hi,

We apologize, but we are unable to provide details regarding the violation.

Best Regards,
AtCoder Support Team

I have requested them, if possible, to be able to recover my username of Roonil03. Hopefully they get recovered.

Update 19/8/2026

Well, that was a lost battle. They stated that they can't recover the username and to make a new account from scratch:
Hi,

Usernames that have been used before cannot be reused. Please create a new account with a different username.

Best Regards,
AtCoder Support Team

Well, that is so unfortunate, but I don't think I will be doing AtCoder anymore :(
