Bringing it back with an internal moderation tool (the Tick System I offered) would mitigate it being bad. That'd be a better idea than being forced to tolerate professional piking that was not agreed to, quest-griefing, rudeness and a myriad of other experiences players routinely come onto the forums to complain about.
As I said before, the only people to truly live in fear of this system are:
1. Aces that would kick undeserving players.
2. Aces that are guilty of piking, griefing, extraordinary rudeness and other kick-worthy feats.
