I don't. When I google for torrents I usually get a bunch of garbage / ad spam sites which don't actually have the content... so I don't google for torrents.
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.
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.
Most top results for "britney spears torrent" are pretty cryptic for a normal user, the actual torrent download button is often obscured by other garbage, if there is one at all.
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. -.-
