Moar Griefing in Vespasian117's house

I log in today and find that somebody has broken through the roof and two floors of my house, leaving flooding water all over the place from the broken skyroof thingies they broke.

Maybe if I put up a sign saying that at least 4 people who have griefed my place have all been banned, would they stop doing it? The glass has been broken so many times like this, people use it as a way to get in.

Edit: after examining the damage, there was dirt placed in the top pool/skyroof area, and also strangely enough a few blocks taken away from the top roof area. Might be two separate griefers, not sure.

I don't see why they bother when their damage can be rolled back within a minute. Omw.

EDIT: Ancillary, banned, if there were any other damaged areas please let me know via PM.
