Yeah, i can't see someone who has been playing on the server longer than me(i think) suddenly whacking on the wallhacks after over 2 years. He's always been a fairly good player and when you play for a team for a while the game changes a lot. Im sure if you looked through some demos of the TWK team without knowledge that it was us wth XAC on, you may think that hacks were involved.

Wallhack can be quite a grey area without decent evidence, because a lot of players get very good at shooting through boxes or anticipating where people will be.
