I got banned from a Minecraft RP + SMP server for "being too edgy".
Which basically meant I didn't have my base extremely close to the others, but instead it was in a forest that was god-knows-how-many-blocks away from the others, and basically because I didn't wear the usual OP armor but instead a cloak from a Mod. (Yes, it was in a modded SMP).
Maybe it also was because when someone started a fire in the forest I lived in I said that I was going to get revenge along with an XD.
