Occasionally I get a message to join some astro site. The most recent is
Astro Gab. I have no interest in them, or any others that are

true e-mail address on NGs. This is not a big problem. It may happen
once every two months. Just curious.

Are you on any astro-related Yahoo groups or have registered on
any astro-related websites? There are a multitude of ways for
folk to get your email address from the above; It isn't only
usenet that is harvested.
