Internet filters seem to have an easy time to detect proxy servers and they will pick them up easily. What worked for me, I put-up a website in the US. I did use PHP at the time and used curl to scrape content from banned sites and serve it from the website. I removed possibly offensive words and presto! Obviously this does not scale well. If you have more problems you can use a ridiculously simple encryption scheme, by swapping all English characters to Armenian and converting back to English at the receiving end via Javascript! (I would not encrypt fully as it might trigger filters of a worse kind).
