First, never respond to spam by posting hate mail to rec.nude. Ever.
In 99.9999% of cases, the spammer will never see your post, and you
will only serve to increase the amount of off-topic posts. (Especially
if you respond to a spam with more spam.) Invariably, people
responding to spam by posting to newsgroups waste more time, money
and/or resources than the original spam did. If you feel the need to
respond to spam, do it in private e-mail. And don't waste your time
responding ineffectively; before you respond to spam, please consult
The Spam Boycott Page < http://spam.abuse.net/> for good, useful advice
on how to do so. A rational, well-directed e-mail response to spam
(e.g. by mailing abuse contacts at the offending ISP) has been shown
to be much more effective than ranting and raving on rec.nude about
it. It is my opinion that nothing will stop spam completely, so if you
are going to respond to it, you might as well do it in a way that
maximizes the positive results.
A moderated newsgroup (alt.nudism.moderated) exists where messages are
reviewed by a team of moderators before they are posted to the newsgroup.
Readers may want to check into that newsgroup for messages as well.
