I was going to say this too, I remember initially using web based proxies like proxify and hidemyass until they were all blocked then we figured out the blocking system didn't work on a wildcard so www.facebook.com would be blocked for example but bypass.facebook.com would not. So a few of my tech savvy friends and I setup a web based proxy on a free host which just wildcarded the sub-domains, I can't remember exactly how we did it but we had that going for a long time. Pretty sure we used a script like http://www.phpmyproxy.com/ http://www.phpmyproxy.com/
