random destroyed things in canada

Went to try and find a new player in Canada to give them torches, and found a destroyed house or two... so decided to look around... and found even more....

Not sure if these are all griefed or unfinished but since some of them have blatantly obvious holes cut in for entry, I'm guessing some were griefed.
Took screenshots with the coordinates up-
just gona put the imgur links so this doesnt take up half a page:

The people responsible may have already been banned, but I'm posting just in case...
