I have a question out of curiosity. Don't get me wrong, I am an Intellectual property fanboy.
Why no Oracle University produced training material and video training available at Torrent Trackers? You can find at Torrent Trackers almost everything, why no Oracle stuff?
Dunno -- honestly I have never looked. I would guess either they are very active in protecting their copyright. You can shut these down by going after the ISPs. The ISPs, when notified, must in turn notify their clients that they will lose their connection if the copyrighted material is not removed within a set time period.
