There's a user named, "Gamertechno" who has been griefing servers.
He's been known to have griefed heal's server before.
But he's completely destroyed Pew's town.
Trading post - DESTROYED
Heal's house- Burned to ground
Cybertails1998's shop - Burned to ground
The only thing that wasn't touched was the bank and the reed place.
Basically, GamerTechno is a griefer and should be banned from all of your minecraft servers.
EDIT: we now have information that GamerTechno was the one burning the buildings, yet Desolation and Zou were the ones breaking the buildings.
Either way, ban GamerTechno, Desolation, And Zou from your servers.
