persianboy12 is a cheater. I reported him. Lichess.org agreed with me. I got my 14 rating points back.

5 games in a row and zero errors. 5 games played perfectly.
Before these 5 games he played a game and he had 22 errors, which is probably normal for him when he doesn't cheat.
The game he played with me was 15+10. After 42 perfect moves he had more time than what he started with, 15:31.
I think persianboy12 has been using a computer.
