So on my vanilla minecraft snapshot server, there is this griefer. He leaves signs around where he has griefed and robbed that say things like "Thanks for your stuff" (He also leaves a name, but its a alias)

I hate his smugness more than anything else, and I want to get him.

I'm building a fake noobshack/base near spawn. I want to set it up as a trap. When he comes to grief it, he'll trigger some redstone or something and it'll put him in jail.

So here is what I want from you nice people, please post your most clever and devious redstone trap systems to help me catch this guy.

sincerely, dinodaw.
