I think i just found one of those limits.

It clearly shows a swastika on the floor made just to provoke me to kill him. (he asked me to kill him after claiming he emptied our vault..fool.)
He had been moving chests and stuff behind cabins 5 minutes earlier and chopped down our apple tree (ooh now we feel griefed sob sob), but even if moving stuff behind cabins is griefing (exploiting) i still dismissed it. A chests is nothing to worry about. But visual provocation (although it does nothing to me personally) should not be allowed. It pollutes the view. It's an eye sore and for some people it might be more.
So what this thread is about is that i think Jorb and Loftar do need a banhammer. Not for exploiters. Not for cheaters. But for people like i encountered here. It's a game, not some blank canvas to spread politics on.
