ok so i made a server and i was fighting some bots, when some guy joins. now thats normal enough but then i see on the screen "Pain changed name to pain is a ****". now i damn well know that i didnt do that, and there was only one other guy in the server. i dont have admin mod. so i assume this guy can control certain server variables even if hes not the host. its probably a half life engine exploit but thers a heads up incase no one knew about it.
