I just realized that Akismet marked 4 legitimate comments, today, as spam. That’s too much false positive for one day, no way I’m gonna wade through 24000+ spam to find out the other false positives.
So I installed Spam Karma 2 instead.
So far, looks like this is one quality WP plugin. I just unzipped in plugins directory, activate it, and it works straight away. Most will find no need to change the default settings, it’s already good enough.
Kudos to Dr. Dave for the excellent work. Also thanks to Eko for introducing me to SK2.
