Tonight I installed James Seng’s Bayesian Spam Filter to help me in my war against comment spam. It’s pretty keen, and I liken it to the Apple Mail spam filter since you “train” the filter to recognize spam. Pretty keen that it works with trackbacks as well. You’ll notice a “(Spam: x%)” appended to all comments now, which is just the plugin identifying the probablility that a comment is spam (or not).
I still need to finish identifying my comments as spam/no spam so this will work to its full potential. So far, so good.
