According to some news sources, HBO is actively poisoning the BitTorrent downloads of the new show - Rome. In addition to an older tactic of offering bogus downloads that never complete, HBO is now obstructing the downloads offered by other people. HBO runs peers that tell the tracker they have all the chunks of the show, but then send garbage data when a downloader requests a chunk. While the bogus peers can be detected, it will take much longer to download shows.
Bad luck to those people who illegally download movies form internet!
