Im curious what, if any hacks, would be visible when you play hardcore and spectate someone.  This is one way that you could spot a cheater if you end up on their side.  You would at least have confirmation that they cheat which could be recorded and posted to YouTube to out them as a confirmed cheater.  I have never seen anything noticeable when spectating,  which is why I wonder if I would even be able to see something like a cheater using codes..
