Hey @Goku2811 It is true some players do violate chess.com's fair play policy, but they really only cheat themselves; these people usually do get caught though. We don't allow discussion of cheating in the public forums though. Feel free to discuss cheating in this club instead though 
https://www.chess.com/club/cheating-forum
If you ever suspect someone of cheating, then just report them: https://support.chess.com/article/209-how-do-i-report-someone or https://www.chess.com/forum/view/general/how-to-contact-support-1
As for the "accuracy" percentage (CAPS: Computer Aggregated Precision Score), many people don't necessarily realize how to interpret this statistic. Here's short chess.com video explaining it a little bit more for clarity:
I'm just curious if other people have similar suspcisions but I think alot of lower level players are using engine moves. I am seeing players playing at levels way beyond 1400 level play often playing moves I cannot even predict or make sense. I think we need to start scrutinizing lower level more seriously as I think cheating may be more severe at lower levels. I've seen players play at 2400 level player with 96% accuracy at 1330 LOL
