"As of earlier today, we have disabled access from users in the US to our trackers. This goes for ALL trackers (torrentbox, podtropolis) we run. This is due to the US’s hostility towards P2P technologies, and we feel with our current lawsuit brought by the MPAA, we can no longer ensure your security and privacy in the US. So, if you’re outside the US, you may notice less peers. We encourage you to add other public, unhampered trackers to torrents you post, in addition to Torrentbox and Podtropolis’s trackers."
This is the second time recently that sites have been forced to block access to US users including last month's shut down of TorrentSpy.
The MPAA believes that the only purpose of these trackers and engines is to share unauthorized copyrighted content, but the owner of IsoHunt does not agree. “We process copyright takedown requests daily, and have done so for hundreds of requests in the past, if not thousands. We work with all copyright owners, and even the RIAA email us routinely. The MPAA is the only organization unwilling to cooperate with us.”
