Why chess . com cant do something against these kind of players?

I mean thats not that hard or a punishment
Thats just playing chess...
Probably a good player is demonstrating how to destroy 2000 players... or they use engine. Lol
They probably used engines. When I was 261 rated on bullet, I played with a 100 rated player but the latter never played mistakes, blunders, or inaccuracies. It was found that the player was (most likely) cheating and violating the Fair Play Rules, so my score was increased to 280 after going down to the 250s.
