VAC (from Steam) seems terrible.

they dont tell you what you get banned for and it cancels all your games and people over at the steam forums say there is zero chance that they'll reinstate your account. sounds like a lot of bs to me.

Yea I agree, never had a Steam ID banned though so i don't really care.

Doesn't seem like they're anti-cheat does a whole lot of good.

I'm using the same account I've had since HL/CS first came out. Never been banned, never had any problems with Steam, so far everything works perfectly fine for me.
