I recently recieved this message from a user: "I'm a regular wikipedia user although i don't have an account here. I think this site is great and it really helps me with my college work. But I recently heard of these people that were talking about wikipedia that they were all programming a hack for it. So after a little while I found it was a spider to hunt down all the pages links and change them to shocks site links or something along those lines. I didn't know who to tell so I just thought I'd tell an administrator as they might know who to tell or what to do. Just giving an advanced warning so you might be able to do something to protect this wonderful resourse. Apparently they permenantly change their ip address using some thing (a bit beyond me). Something like that. I just didn't know what to do. I hope I didn't embaress myself here. Thanks for your time."
