Matt, I tried spam-stopper in my WordPress 1.2.x installations, but the hooks
appear to neglect the plug-in. Spam just kept flooding in (more easily than
ever since other protections were down) and there was no notion of spam
flagging. I also set up a test-bed at http://www.schestowitz.com/Spam/ with
some inbound links. I suspect it does not attract any spammers though.
