This is a letter on behalf of my roommate and close friend, **not_visible_for_all**, who recently got banned from Codeforces.↵
↵
I live with him and know him very well. Over the years he has solved over **1900 problems** on his own. He has never copied or used any other code and each solution was created by him alone.↵
↵
It's a sad but true story. In recent contest, he used a code from his second account [user:Baishakh2,2026-05-08] and in the same contest submitted the same code on his main account not_visible_for_all during contest time. ↵
↵
He didn't realize that this is against the rules of Codeforces. When he saw there was a problem, he accepted his mistake. He is truly sorry.↵
↵
The code was 100% his own work. It was a mistake and was not done to cheat or to gain any unfair advantage.↵
↵
He already sent an official appeal to the Codeforces support. Please reconsider not_visible_for_all. He won't do this again.↵
↵
Thank you.↵
