I'm seriously thinking about quitting this website; cheaters never get punished. It looks like chess.com doesn’t have a good cheater detector. "People" that have the same elo as me and somehow dominate the game completely, always finding that super difficult move to see in critical positions... Like, if you’re so good that you can play amazing for 40 or 50 moves, why are you 1800? When I report these players, nothing happens. Maybe someone will accuse me of having a "skill issue," but seriously, it is pretty clear the difference between a good 1800 and a cheater.
