The discussion about cheaters on xfire has never been on the level it is now. Let me start with some common quotes found here on xfire to give us some first impression about this issue.

zwitter:
i wonder if they gonna be added 2 cheat list on clanbase. so far bond and any
of recently cought players werent x]


rbnt:
PLEASE make pbscreenshots. we can all say ye it LOOKS like a wallhack but its
no use :S


fONG:
why so many ppl cheating in teh last time ?
ur dicks getting smaller every day?


Rezonnnnnn:
ban!


Wabbito:
So like if I set those cvars and join serva I get banned for having those cvars?


Roach:
Wow another (CVAR) #9001 on telenet -_-''
We all know by now this PB update doesn't work... Accusing someone for cvars is bs.


chucki3:
Servers don't edit cfg files. Players do.


TosspoT:
If the accusations are correct then its a crying shame that clans are packing in rather than playing the game, it would mean the cheaters had won :(
GL to underscore, really nice group of guys hope to see them back.


maTze:
any proof? i mean real one?
