He has hidden name, chat and some Debug Monitor info (and he changes profile name like every time he connects to new servers) He shows this in monitor: *Murders *Bandit Kills *Blood He does not reveal what server he connects to. I think the hacker(s) got his name or something by mistake, and by that some GUID or IP or something like that (I don't know shit about these things, but this is my best guess) Right now he is trying another Arma II copy and see if that helps..
