I don't know if the spam filter will work better now that I tweaked it, but we'll give it a try. Please excuse any inappropriate content that appears briefly over the next couple days.

As many of my veteran readers know, I'm fundamentally against challenge-and-response validation as well as visiter registration, so as far as spam goes, I have to rely on good old fashioned content filters. Up until the recent upgrade, the Akismet service had reduced my comment spam from 5-10 per day to 4 or 5 per year. However, Akismet apparently doesn't get along nearly as well with MT4.21 as it did with MT3.x.
