Compliments: Excellent plugin. It's totally eliminated comment spam on my blog without any annoying CAPTCHAs or other stuff that annoys visitors.
Trackback/Pingback spams are a different story, but Akismet catches all of these so far.
Keep up the good work!
Feature Request: Add the ability to reset the counter of spambots caught as I have occasionally tested the filter to see if it works and I don't want to have my tests count against the total count.
