After The Pirate Bay got banned by major ISPs in the U.K. I was thinking about how they might help users circumvent the block.
Seeing as the site still appears in Google, Google is essentially hosting a copy of The Pirate Bay in it's cache available for all UK users (http://google.com/search?q=cache:http://www.thepiratebay.se). Which makes you wonder why they don't ban Google and other search engines. That aside...
I think this would be an interesting experiment - if The Pirate Bay put direct torrent links in their meta descriptions, they would likely start appearing in Google.
That would then essentially make Google == The Pirate Bay. As all The Pirate Bay does anyway is host the torrent links and no actual content.
What are your thoughts?
