Usenet Posting Privacy
Usenet offers people around the world a fantastic wealth of free resources. It is a place where everyone can offer their experience and knowledge to others and benefit from others’ knowledge and experience.
However, there are some people out there who are not so friendly towards other users and may abuse their personal information (including name and email address). This also applies to spammers, who use computer programs to look for email addresses in posted Usenet articles so they can send spam.
You should be aware that most newsreaders automatically include your name, email address, and an optional signature as a part of the articles you post. The newsreaders usually put your name and e-mail address at the top of the articles, and your signature file at the bottom
If your identity in Usenet is a concern to you, or you don’t want to give spammers a chance to send you unsolicited email, you might consider using a pseudonym and a fake email address when posting. If you disguise your e-mail address, the spammers scanning for email addresses will not get a correct email address for you and other unfriendly users will not be able to take advantage of your personal information.
