I did a search for allinurl:webmasterworld.com, and some of the pages it lists arent on webmasterworld... They're on other sites, and theres some pretty strange entries, check it out for yourself.

It looks like google still isn't filtering out proxy servers. The other results are normal...any pages where "webmasterworld.com" appears somewhere in the URL are valid results for that search.
