Hey it's me Villager. I came on earlier today and majormc1702 was on. He said his house had been griefed by MCPrimed, and fortunately he repaired it. I (literally) flew over to the public building and skyscraper that I was still working on, and found a sign in front of it reading "MCPrimed's Home" for the public building and "MCPrimed's Palace" for the skyscraper. I walked up the path that I had built and there was another sign. It read: "People Allowed: MCPrimed" and then some other users I don't remember. In the public building, I found some chests locked by MCPrimed, which means they were certainly the one who placed the signs, as no one can lock a chest for another. I took down all of that before I thought about reporting, though, so a screenshot would be pointless. I kicked MCPrimed from town so they can't cause any more damage.
Unfortunately, I can't prove anything because I removed all the evidence before thinking about reporting.
