Thanks to the poster and responder. I just did this for usenet posts.
Now my question is: do I have to do this for email also?
No, you don't have to, and you generally should *not*. If you do,
and you send someone a message, that person would not be able to
reply directly to you (the reply would go to the fake address).
The only way someone could reply to you would be if he knew your
real address and manually inserted it into the message.
Can spammers
harvest my address from email also, or just usenet posts?
Spammers can't harvest your address from E-mail unless you send
them E-mail. They have to get the message to see your address.
Anyone can get a newsgroup message, but only the addressees get
E-mail messages. That's why you need to do this for newsgroup
messages, but not for E-mail.
