Server is ppsucc69. Not a joke. User RyanUwU entered our game and destroyed everyone's house using flint and steel and lava buckets. He somehow managed to get operator privileges and light everything on fire. I didn't screenshot the chat, as I was too concerned with trying to put out the multiplying fires, but I did take before and after screenshots of the house me and my girlfriend built before he griefed us. We had about 5 people regularly playing on the server. Any help in this matter is greatly appreciated, thanks.
