Even though I’m already using Bad Behavior with blocks 99.99% of the bots who try to access my site, there is still the occasional person who manually spams my site. So, to totally lock ‘er down, I’ve installed Spam Karma 2 – Reloaded.
It’s a VERY sophisticated plugin that makes sure that no spam whatsoever gets onto my blog while not getting in the way of most comments (a few here and there are still put in my moderation queue as it’s not sure on them).
Anyway, if you run a WordPress powered blog, I highly recommend you install both Bad Bahavior and Spam Karma 2. It’s not hard, (very easy actually), and you won’t regret it. 🙂
