Spammers can create any number of spam-OPs

If they do, then relying parties can use the usual
measures - for example a blog can auto whitelist any
commentor who has had a comment approved, and also auto
whitelist his OP, blacklist known spammer OPs, and
graylist all unknown OPs.

People with a whitelisted OP get their comment displayed
immediately, but flagged to be examined by moderator,
people with a graylisted OP get their comment held for
moderation, people with a blacklisted OP get 404ed
