As far as i remember, only Pirate Bay and Newzbin2 was blocked (Newzbin2 has shutdown). The Promobay was blocked but was blocked as a mistake as it was originally owned by the Priate Bay but now are not assoicated with them.
I dont think there will be a list as it isnt many.
I mean, what about extreme porno sites for example? Terrorist sites or whatever.
I have never tried to visit either, but it seems to me, that if anything should be blockedl, then that's were you'd start. Not with TPB which is only one out of thousands of torrent sites.
(How long until all torrent sites are blocked.... ? )
Oh well. Don't want to give Virgin any ideas, and unfortunately suppoirting freedom online means you can't pick and choose so while I personally find such sites revolting, I am not in favour of them being blocked.
Nothing like that will be blocked, If its for example to stop kids seeing said sites, then you would need to install a parental control software to block certain sites. The only reason torrent sites are getting taken down one by one is because of the music industry throwing their toys out the pram.
