Hi dear codeforces users and MikeMirzayanov ! I recently found out that a person who lives in the same city as me bizimlesen cheated on Codeforces using an alt account. He solved all div2 problems from A to E. I don't know exactly how he cheated, but I think someone else is sending him the codes because I doubt that AI can solve a div2 E problem. His main account is xosqedemrufo, you can look at his previous submissions from contests and see that he also cheats with his main account. This user has created multiple other accounts and most of them have been banned by codeforces, either way I just wanted to address this issue. I hope this posts reaches codeforces admins and someone takes responsibility for this. If someone wants more proof that this user is cheating they can look at their submissions or dm me :)
