Googling "britney spears torrent" is just going to bring up a different torrent site than tpb.
The clear solution is for UK ISPs to ban Google.
Besides, if they block pirate bay, it's only a matter of time before most other popular torrent sites are also blocked. Sure mirrors will pop up, but they won't show up on the first page of a google search's results, at least for a while.
VPN is the way to go.
..try this: "content name" + magnet.

This will return more spam-riddled results over time as magnet links grow in popularity (if more sites follow TPB and go magnet-only), but it'll do for now.
TPB would know how big the effect will be, I'm curious if they publish data on that.
in any case, the whole copyright infringement thing is really trivial. As soon as you disable one method (here's to you Napster), new ones are only going to pop up. If the authorities were serious about cracking down on IP infringements, they'd revamp copyright law to reflect current technology and culture. -.-
(I know that was sarcasm btw)
