Why bother reporting? They will just open a new account and keep cheating. That's why I won't play rapid here anymore. Its full of engines at higher levels and there's nothing anybody can do about it.
How to Report Suspected Computer Usage?

I play rapid too often here..... Is it too bad??

What's the appropriate channel to report this?
Suspects should be reported at http://support.chess.com/customer/portal/emails/new
To discuss various aspects of cheating, join the https://www.chess.com/club/cheating-forum club (note that public accusations are not allowed there, or anywhere else).
