I have entered an Akismet API key for the forum. No problem with that. Question--does Akismet check every forum post as it is made, or only the first X number of posts (as set by "Maximum Messages to Check for Spam" in the admin settings)? I could see bumping into my top monthly limit on the free Akismet service if it were scanning every incoming post. I would think after five or ten messages, we could pretty much determine if that new member were a spammer or not.
