Anti-commercial?  Anti-death-of-the-net I would rather hope.

Like may other experienced net.users fed up with unsolicited e-mail and
Usenet abusers wasting bandwidth with spam, I'm taking an active approach
to keeping my 'net time enjoyable.  Besides the very accurate
spam.abuse.net site and the very funny (yet deadly serious) MMF Hall of
Humiliation, here are other sites that offer ways for you to keep out the
spam:

<http://members.aol.com/macabrus/faqs.html> (who maintains net-abuse links)
<http://www.slipstick.com/exchange/> (Find the antispam plugin for Exchange)
<http://www.junkbusters.com/> (Legal defense against spam)

And just to keep everything in perspective:

<http://www.spam.com/> (Hormel's own site)
<http://www.smalltime.com/nowhere/findthespam/> (The original and the best)
