O’Reillynet has reported that you can use Google as a free proxy. Basicly, you just translate from english to english or whatever other language you understand. The idea is that google is {almost} never blacklisted. So you could access any site you want through g00gle.
here's a quote from the original article:
What’s the purpose for Google as a proxy? We often use office/school/university connections, usually those services are set to provide more safety, blocking the access to undesired web sites (the “black list”). What you can do now is use Google translator service (language tools) as a proxy to bypass the restrictions set for our connection!
