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.
