You called it. Their response is “banned for claim spam”. When I provided pictures and asked how my tiny sandstone base was claim spam, I received the generic "“it’s your responsibility to make sure no one in your clan is abusing game mechanics or partaking in continued harassment” message.
They provided no other details and stopped answering me. Leaving me absolutely puzzled.
I still don’t know what I got banned for.
This is a PVE server. The base didn’t have much in it, and was infrequently played (it was for RL friends who rarely logged). It was still sandstone. It was in a rarely traveled area. It didn’t wall off, surround anything, or block resources. I know what the Official Server Rules are…
And I still don’t know what I did.
(Oh, didn’t mean to take this off topic. I’ll stop now)
