205.188.209.39 vandalized something else, then removed the note on the vandalism in progress page that said that he was vandalizing. I blocked the address (vandalizing the vandalism page is cause for immediate blocking), then looked it up and found that it's an AOL proxy and a neighboring proxy was already blocked for some other vandalism. He will probably be back from yet another proxy. Don't hesitate to block if he vandalizes the vandalism page, but once he gives up, they should all be unblocked so that someone else can use them.
