He has admitted to cheating, there's no debate about that. But he maintains that he has cheated in two isolated incidents, at age 12 and 16. These are mistakes, and given he is a titled player, very serious mistakes.
But, beyond barring him from chess.com (a platform with whom his chief accuser has significant business ties), they've absolutely dragged his reputation through the mud many times over. All of this, it seems, based on a "feeling" that Magnus had OTB on a particular game (for which no evidence of cheating has been found).
It wreaks of witchhunt, and has damaged his reputation in a likely unrepairable fashion. I understand he's made mistakes, but it seems we've all tacitly agreed that it is ok to drag someone through the mud because he seems a bit obnoxious and made mistakes while a child. I hope we'd be better than that.
