StupidHijacking

Here's a simple example of how the proxy sites hijack listings.

72.51.33.237 [server1.stupidcensorship.com.] requested 2 pages as "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)"

Yes, that was really Googlebot that tried to crawl my server via the proxy hosted on that server.

Amazingly you won't see any links for Google to crawl my site or any other site via this proxy server which is why I always assume there is a cloaked list of URLs being fed to Google as this happens all the time from all sorts of proxy sites of this type.
