You can try to visit
http://www.messengerdiscovery.com via
an anonymous webproxy, but you have try a few of them
because not all functions will work (e.g. some JavaScript), but most pages will be fine.
If you try to translate the dutch site
http://www.anoniemsurfen.nl
into english you get a very funny language (it looks like an south-african accent to me) because machine translations won`t work.
There is a another dutch index site in english! about the subject:
http://anoniem-surfen.eigenstart.nl/
There`s not much to read, but if you understand the subject it will
help you to acces blocked pages
