Except that comment spammers do not seem to be counted by Honeypot on your dashboard, correct? (I have well over 1500 comment spans from a single IP in Sweden, and Honeypot shows "0" spam on my site, despite me adding the honeypot link to the same page accessed by the spammer.)
http:BL seems to be doing nothing for me. I'm sure it's something I'm doing wrong somewhere, but neither the honeypot forums or plugin forums seem to respond to the question, and I've read all I can find on installation/configuration.
I removed http:BL and installed "Bad Behavior" and Bad Behavior Log Reader in its place, and now finally see actual results in blovking the comment spammer.
Check the "Bad Behavior" stats right at the very bottom of my blog pages...(all from the SAME comment spammer!)
