content: The way I understand it is that the flow of leaked/uploaded content goes like this: Private FTP servers (exclusive as it's invite-only) or Private Torrent Trackers (similar deal) > Usenet newsgroups (exclusive as it costs $$) > Public Torrent Trackers (anyone can use them). http://lifehacker.com/5897095/whats-a-private-bittorrent-tracker-and-why-should-i-use-one ^What I read to understand what you meant by private trackers. As it mentioned, they aren't for everyone (but neither is XDCC via IRC). Let me clarify my prior comment with a correction... If you ever are interested in looking into XDCC via IRC again, nibl.co.uk for anime and ixirc.com for movies/tv shows.
