Etisalat/TRA today blocked Torrentspy.com, one of the leading torrent indexing sites. It sure did have adult content, but most torrent indexing sites do have adult content. And Etisalat seemed to be filtering out the adult content on it to an extent.
This blocking sends out a message to all those using peer-to-peer sites and software (torrents, Limewire, Kazaa, etc..). P2P traffic consumes most of an ISP's traffic and and clogs its traffic. In Etisalat's case, be prepared for the worst. Technology thats filters p2p traffic is already in use in the West, how soon Etisalat implements this filter is anyones guess.
