Most anti-piracy outfits and other organizations that track BitTorrent users rely on information they obtain from BitTorrent trackers. This is an easy and convenient technique to gather info, but also one that can be circumvented.
Let’s assume you want to download ‘Steal This Film’ without being spied on by third parties that monitor the download. Impossible? Not really…
Pretty much all BitTorrent clients allow users to remove the trackers from a torrent before downloading. In uTorrent you can do so by clicking the advanced button in the torrent opening dialog box. You’ll then see the trackers included in the torrent plus some other info.
If you want to go tracker-less you’ll have to delete the trackers and make sure that the DHT, Peer Exchange and Local Peer Discovery boxes (see screenshot) are checked otherwise you you won’t be able to download at all.
That’s it…
We have to note that it’s by no means impossible to track people who download without a tracker. It’s just harder to do so and thus far we haven’t seen evidence that DHT tracking is being used.
