It's not bad for the most part, not enough people in free for all a lot of the time.
The only real problem I have is the lethalgaming servers. The admins there get butthurt if you start killing them so they'll ban you and claim you're camping spawns. So yeah, great community, as long as you stay away from lethalgaming, then again, who wants to play on a server full of sore losers anyway? I imagine they'll piss off the wrong person one day and be dealt with by Anonymous, much like the way Playstation Network was dealt with last year by Anonymous.
