I don't know. Just remember reading some headlines somewhere. Was playing the other day and people arguing back and forth in the chat ending up dead almost instantly the whole match and watching the wallhackers do their thing. I uninstalled the game not long after, if I want to play with a bunch of hacks being used I'd rather go onto counter strike source where there are people actively banning the hackers than to be at the mercy of the other team kicking them which never seems to happen.
