So I logged in earlier to find 3 people, all with similar skins, griefing south. I got a couple of their names "Usmarine99" and "Harrisonbitzis" but the third guys name i can't recall.
They completely destroyed the heart at south portal, attatched a huge dick to goku (which we took down), turned the "SPARTA" city sign into "Boner" and did heaps of other random stuff.
Probably be best to find out everyone involved, ban them and roll back :( Twice souths been hit in one day by griefers..
