PrivTracker allows to share torrent files just with your friends, nobody else. Unlike public trackers, it shares peers only within a group which is using the same Announce URL. It really works like a private tracker, but can be generated with one click of a button.
That’s kind of cool but why not just share .torrent to your friends? Does this have rss-like function
Because you either need an announce URL or publishing your torrent to the DHT for your friends to be able to peer with you.
Seeding copyrighted material using a public announce URL or the DHT will get you in trouble in most western countries.
