Believe it or not, I get hundreds of visitors from young adults looking for help by-passing their schools filtering of the MySpace domain. These hits come from a popular query on Google; MySpace Blocked. Anyhow, I thought I'd try to enumerate a few of the methods of by-passing a school's domain block filter, maybe it'll help a few kids survived the school day while failing all their exams. There are three primary ways of by-passing such a block, whether myspace.com or other.
A Web-browser proxy is a Webpage that allows you to type a URL and redirects all the responses from the blocked domain thru the proxy's domain. A list follows. I'll post a larger list in the comments.
Each has different features and some require you to pay to enable some features. Try them out and find which is best for you. BTW, use at your own risk. I don't warrant that these sites won't try to install some malware.
HTTP proxies tend to be more difficult to use for non-geeks and they are easily blocked by competent school IT techs. I won't explain them here, but if the Web-browser proxies don't work, then try these.
The worst solution is to run the sites through a language translator. Not really a good solution because the translations tend to be awful. A list follows.
Anyhow, good luck and I pray you don't fail all your exams.
