Why do you torrent instead of using Usenet?
1. I have to pay for access to a usenet server. The entire point of piracy is that I'm not paying.
2. I need special, poorly documented, and practically undiscoverable tools to: access Usenet, download a file split over 2million posts, reassemble that file, extract the file from whatever esoteric compression algorithm the uploader decided was best that week.
3. I need to find a Usenet server that carries binaries, then, I need to find the individual groups that have the content I want.
On the other hand, thepiratebay has 99% of everything I want, and what it doesn't have I can usually find pretty quickly though Yandex or sharemania.
2. sabnzbbd or nzgget are hardly poorly documented or undiscoverable.
3. you need to get an indexer which handles all those files over 2 million posts. the software in 2 will put them together for you with minimal effort.
i would recommend a premium indexer as they are quite cheap but there are free available.
i would also like to note that since you're not using a torrent you can't be done for distribution of copywritten material to the same scale as you can for a torrent.
