NewsBin is a usenet robot for downloading binaries.
Simply put, Newsbin will contact your news server and download a list of available newsgroups. You then select what groups you like, then it will read every message. If a message has a file, it will download it, in accordance with a myriad of filters you can set up.

Super easy to use, you can easily get loads of pr0n, warez, games, hacks, etc. We used to use it to get PSX games and entire movies in VCD format.

It does cost $35 or so, and is currently only running on Windows.
