I haven't installed it, but the script looks good. I clicked around PirateBay.org on the following pages
1) Search Results page
2) Page with torrent link to download
Observed was that the objects on the page with id 'ads' and 'ibario.com' have been removed.
Also, I checked out where ibario.com link is being imbedded - it's a toolbar (I don't know if it has spyware or not) that's being embedded in the download torrent page secretively right underneath the download button. Naughty naughty PirateBay.org
