I was a warez guy back in the day but that got risky.
Just like Torrentz and Warez, they used to host the torrents themselves. A year ago, they now use an aggregating algorithm..the same way anilinkz or animefreak shows free anime: they become the 3rd party braodcaster and NEVER host the animes themselves, even though they are copyrighted, complete with disclaimer in case they get sued.
Ever heard of mininova? They were forced by the Euro arm of the RIAA to stop hosting the tors, and same thing is happening to isohunt. Isohunt doesn;t now list the torrents BUT only for US IP’s. BUT if u use an anonimizer like anonymouse.org, you will see it’s the original database of torrents listed.
..that’s what I heard from the neighbor’s kid (cough)
