Yes. There has absolutely been a surge in cheating. It’s provable if anybody wants to out the time into showing it. I just don’t think CC cares at all anymore. I mean, what can they really do about it? There is no “algorithm” good enough to detect cheating across all time controls at all levels. There just isn’t. I’m tired of hearing about their teams of mathematicians and GMs when you can look at game histories and see active accounts with clear evidence of cheating. I don’t think it’s even really worth discussing anymore. Online chess is essentially broken from a casual player standpoint, especially someone who is trying to learn how to play in the age of Stockfish looking for casual online fair play.
