I don't know whether they hack or not because I kick both of their asses regularly and would hate to get accused of such a thing myself. However, I have noticed for quite some time now they have an uncanny ability to take a server down from 24 to 2-3 players within one map rotation, that's not cool. Also previously if you ran off so many players and ruined gameplay for others (referring to iguess and BBQ) those people would be removed from the server's for the betterment of the player's on the server and to keep it filled.
Although it seems a lot of things have changed with time, It use to be hackussations without video or admin proof would be met with a warning or kick. Nightly people who know better (XI members not even BBQ or IGuess) accuse other's of such things to the point they too run player's off of the servers with their bitching and complaining. The rules are few and simple, but it seems some people including our member's don't care if they ruin it for others.
