I joined Chess.com to play with some friends. I got into it and soon was watching a lot of videos. Next thing I know I'm banned. They never exactly told me in any specific terms the reason. But they have a magical algorithm or statistics that say I must have used outside help, though I didn't. Clearly they do this just to try to take your money and run. From everything I've read they have lots of actual cheaters with fake accounts they do nothing about. Yet they ban real customers who do nothing wrong. Stay away!
