If you're in the United States, you're already paying for a spam-fighting
service (via your taxes).
You can foreward the email to [log in to unmask], and presumably they'll track
down the miscreants that
sent the spam, and initiate a Ruby-ridge type response. ( I can dream,
can't I? )

FOR RELEASE: JULY 14, 1998 FTC Unveils "Dirty Dozen Spam Scams"

          The Federal Trade Commission today released a list of the 12 most
          common scams found in unsolicited commercial e-mail -- spam. The
list
          was culled from a sampling of more than 250,000 junk e-mail
messages
          that consumers have forwarded to a special FTC mailbox
          ([log in to unmask]) set up to collect spam.
