I've noticed increasing levels of vandalism via anonymizing proxies. We turned off the automatic proxy-scanning some time ago because of complaints by the clue-deficient who saw this as potential attacks.
The Tor anonymous network (http://tor.eff.org) keeps a list of known "exit nodes": http://www.noreply.org/tor-running-routers/

Not all of them will do port 80 though, and not all of them will connect to wikipedia. I collated a list from the dirservers (which do list the exit policy) and open-proxy blocked the ones that were able to edit wikipedia. It's a little soon to say, but I think it has stopped most of the Tor-vandalism.
