Shamwow10101 and the TNT

As I'm typing right now, a guy named Shamwow10101 is blowing up the server and no admins are on. He's ranked peasant and I'm sure he's not allowed to blow up the spawn. As soon as anyone sees this, get him banned, get on the server, and get a rollback! Please. I'll try to go on now to get a screenshot.

I got on again, got a screenie of brainstorm123456 flymodding and building a 'T' with TNT. He says he's a hired demolisher. I do not believe him the slightest. On second notice: I have lost track of whether the first griefers name was Shadow or Shamwow. Try both. I can't figure out this system of yours with images, I'll try later.

EDIT:
- Confirmed as Shamwow10101
- Got a screenie of his TNT tower too
- Trying to get more screenshots

EDIT 2:
- They seem to have gone off
- Got some more screenshots. Trying to figure out how to post them
- I didn't manage to get Shamwow and his TNT 'creations' on the same screenie. However I did catch both griefers flying with TNT in their hands.
