I own my own Teamspeak server from home. Someone joined as a ServerQuery (Guest[Temp] i think). I have not given anyone server query logins and only my friends have admin and they don't even know how to login as server query. I was unable to ban the person and they joined for a bit before i shut down the server. When i started the server back up they were still on it but left a minute after. I'm not really sure what to do.
