Akismet Black Hole? (no comments caught)

Using WP2 and Akismet with Bad Behavior. Working well, perhaps too well? My site gets little traffic and very few comments but with WP 1.52 and SK2 I had a steady stream of casino, drug, and other spam comments showing up. Probably 10-20/week. While I’m thrilled to not be getting those, there was some solace (and joy) at seeing all the killed comments in the SK2 logs. Bottom line, I’m wondering about false positives and why I don’t see more spam reported as caught. Great product though!

TIA,
