First of all My Online mode is set to True. I even deleted the whole server and re done everything (Backing up my world and plugins ofcourse). It's happened with three players. I banned them then they connect with a different name. They ban evaded more than 14 accounts. One admitted its a NameChanger hack hes using. But how do I stop this madness. I'm not going to white list so anything I can do! [EDIT] Baning IP is such a dumb idea too. They can reset their router..
