i think what we need are some of the really really good people here to create a throwaway server, (no VAC and passworded so noone else can enter) and then record a series of demos, each highlighting what different hacks look like and how to tell the difference between skill and hacks. there could be a wallhack one, aimbot one, etc. etc...
then sticky it in the rules section/ban request section so that people would be able to tell what to look out for.
