At one point he gave himself and some other people the * perm. i ended up tracking them all down. removing all perms they ha banning them ip banning them and we were fine. for 2 days. than somehow magically someone the * perm. but it said give by console and no one has access to console besides me. I was reading this in logs. but my friend calls me on the phone while i was asleep screaming to get online because they game back and deleted all worlds and etc. luckily i was able to get the worlds back. took me a couple minutes to fix the griefing. and they removed all mines but i rolled back globally 24h which somehow fixed all mines i created. But main thing here is that this just happens. none of them are online, none of them and bang unban unbanip ban admin deep admin remove * from admin all of that in less than 2 seconds.
