This is what

What is the punishment for breaking the law? Or is it just a filter and has no legal weight behind it?
As for advice on what to do, the easiest would be to download the Linux live CD for backtrack 2 (or any other distro, linux Mint is what I use, but backtrack has more network tools pre-installed). Then try the anonym.to site, but they can block that. If they do, you may need to install Tor (save it to a USB drive if it doesn't come on the backtrack live CD.) That isn't as easy as it sounds (it should be easier, then again I haven't tried installing it in linux and the last time I tried in windows was 18 months ago.), but it should definitely work.
