Cheating is rampant on this site . there is no question about that. Its so bad Danny and the rest of the GM 's dont even play the public anymore. Too bad as otherwise in so many ways the site is great.

Cheaters are banned when they are detected. There are various tools that are used to keep them from returning without permission; these tools are familiar to anyone who has run an online forum.
However, discussions of cheating in the main forum is not permitted, as it tends to become very heated and result in lots of public accusations, many of which are completely unfounded; you might be surprised how many cheating reports we get about low-rated players after a game that was a complete blunderfest. If all these reports were aired in public, it would just cause an ugly flame war. I am therefore locking this post.
To discuss the matter of cheating further, or to learn more about cheat detection, please join the Cheating Forum: https://www.chess.com/club/cheating-forum
To report a suspected cheater to the Support team, please select Report Abuse under the Help menu, or use this link: https://support.chess.com/customer/portal/emails/new. All reports are investigated, even if there is no immediate visible action.

I played bullet,the other player time stopped at .06 second,I had been premoving ,I had a 15 second advantage,how come,his clock stopped,?!! It was a 1 minute game ,no increment. Very annoying.
