The people who package the torrent, not the site / tracker itself. Most private trackers have no ad's. Though with Isohunt I can download it as easy as one click once I pick the desired torrent. I thought most people used adblock and no script these days?

As with usenet yes they have an affiliate system. Though you don't make money uploading the content to usenet. Torrents or usenet are not PPD.

My posts were based more less towards the uploader of the torrent. The site does need ad's to survive I agree with that completely.
