Usenet, also known as "news", "newsgroups", or "discussion group." Usenet is a huge collection of newsgroups about every and any topic you can imagine. Once a person posts to a newsgroup, it is transmitted to news servers all over the world for other people to see.
Spammers often extract email addresses from newsgroups, so many people have stopped using usenet or hide their email address when posting.
