PeerWeb
PeerWeb is a site dedicated to indexing files on the Gnutella2 network. The site itself does not host the files, but collects and sorts special Magnet links, which contain a hash value to identify files being shared by other Gnutella2 users through clients such as Shareaza. By only offering these unique links, PeerWeb is able to offer games, music, software, movies, e-books and television series and still remain within the law of its home country. All Microsoft products however, are prohibited and can result in an account suspension if this rule is breached.
