I logged on today, to my friend screaming at me saying that JMCguy was getting death threats and that Struct Build Team HQ was greifed. Now I was confused when I saw the "greif". It said DIE JMCGUY DIE -ItsJerry (I will include the screenshots) and a whole level of my building got destroyed? Also, the staffboard in the lobby was made of wood and full of signs and heads but now it is made of quartz and is now blank. One of my builders built the Build Team mascot on the roof (Its a legendary chicken) and now that's gone. Apparently somebody built a male part xD at the top and the server staff only saw to that. :/
Sorry for a late reply, but why would Jerry do this in the first place? He'd have no reason to so it wasn't him.
Jerry is innocent - someone added on your plot whose added/trusted would've put that sign then put it's from ItsJerry, even though he didn't grief.
