As an extra solution you could leverage on the new flood protection mechanism I introduced in Drupal 4.6. See flood_register_event() and flood_is_allowed(), and check the contact.module in CVS HEAD to see how it can be used.
Unfortunately this will not help, as your flood protection mechanism is per IP. The spammers are using an unbelievably large number of proxies, and each comment seems to come from a new IP address. What more, the contents hold random data, so simply comparing new comments against old to look for duplication isn't often even possible. -Jeremy
