It should be noted that in the UK they are actually trying to block websites--specifically the Pirate Bay--that promote copyright infringement. This in the birthplace of parliamentary democracy.
It's interesting. The only site they are blocking is the Pirate Bay. Everyone knows they are faaaar from the only torrent site out there. So it seems clear that this is their test case, to see what they can get away with--and what will work.
The British Pirate Party is hosting a proxy to the Pirate Bay, which is annoying Hollywood. They have asked them politely several times to stop. The Pirate Party, of course, told them impolitely to fuck off. Currently in the UK, the court orders ordering the blocking of the Pirate Bay apply only to Internet Service Providers. Which is dumb, of course, because anyone can be an ISP, which the Pirate Party is busy demonstrating.
So it'll be interesting to see how this plays out over there.
