Spam Karma 1 beta 2 has been very good to me, only letting through a couple false negatives and almost no false positives. But it’s good to be pro-active about comment spam. Spam Karma works.
I just installed Spam Karma 2. First impression: The new Spam Karma has a lot of knobs and buttons! This is industrial grade stuff.
I even went all wacky and turned Pingbacks and Trackbacks on.
If your comment gets inappropriately eaten by SK or you’re having any trouble, ping me.
