sc.surbl.org has the advantage of the many SpamCop users
reviewing their submissions for legitimate looking domains and
unchecking them before they click Submit.  So far it seems to
help a lot.

However if *any* of the domains in a spam are on an SURBL list, the
entire message will get tagged as spam (for mail servers using
SURBL of course).  The more spam domains the spammers add,
including their spamming rivals, the better our chance of tagging
the message as spam.

Score one for the good guys if they try to take out their
competitors this way.
