To win because they can't win without an engine and also to feel better about themselves and hide the fact that they simply cannot play. If they are good players and they are cheating, then it is because they either want to get on the chess.com leaderboard or they want to be able to play GM's since cheating will give them such a high rating that they could be matched up with GM's
Cheaters on the site
Chess.com takes cheating very seriously: see https://www.chess.com/article/view/chess-com-fair-play-and-cheat-detection, https://support.chess.com/customer/en/portal/articles/1444879-fair-play-on-chess-com-what-you-need-to-know and https://www.chess.com/blog/DanielRensch/cheating-on-chesscom.
Cheaters are banned when they are detected. However, discussions of cheating in the main forum is not permitted, as everyone is entitled to the presumption of innocence, and because accurate cheat detection requires a degree of understanding that many people don't have. The Cheating Discussion Club at https://www.chess.com/club/cheating-forum is a great place to learn more about it.
We also very much appreciate accurate reports of suspected cheaters: please use Help --> Report Abuse, 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 am now locking this thread.
Thanks,
