As it says in Leviticus : 'Cheating is an abomination before God..but is allowed if you surname is Clinton...'

A player i just played seemed to be cheating using not only an engine but some sort of time hack as well. Can i name this player so everyone can know who it is?

Yes...just create another profile, and use that one.

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.
Having said that, public accusations in the open forums is not the way to address these concerns, so I am locking this thread; please report any suspected cheating to the Support team via https://support.chess.com/customer/portal/emails/new and trust that it will be investigated, even if there is no immediate visible action.
