Very interesting article. I however have a few concerns about trying to block websites with illegal content. Illegal downloading can potentially be a good thing if the downloadee has every intention of paying for the album.
For example, I illegally downloaded James Blunt's Back To Bedlam (I know I know ) and The Very Best of Beach Boys not too long ago, mainly just to see if I liked the songs and the album as a whole. It turns out that I did like them so much, I actually went out and bought the albums to support the artists.
Had I not downloaded these albums I would have had no intention of buying them. I did it not because I wanted to take money away from the artist - But because I wanted to see if their albums were decent enough for me to make a purchase, and I liked them, so I did.
If I bought the album without knowing what the album is like and I disliked it, I would have gave the album a low score on Amazon etc. and explained why, since I paid money for a crap album, thus alienating other potential purchasers from buying it. If I had downloaded the album illegally and disliked it, I would have just deleted the music from my computer. No worries.
