For the last several months, keeping this blog spam-free seemed like a full-time gig. Every time I logged into the admin page, there were a dozen or thirty new spams about prescription drugs, gambling, credit reports, or methods of enhancing elements of one’s physical person. And those are the ones that made it through my keyword blacklists! Cleaning them up took detective work, and that takes time.
Enter the Wordpress plugin “Spam Karma 2“, or SK2. SK2 is a brilliant piece of software–I half expect it to become intelligent and evolve into SkyNet and start sending robots back in time to install itself on Wordpress blogs throughout the blogosphere. In the three or so days I’ve had it installed, it’s stopped every single spam comment and correctly let through every single valid comment. Okay, okay… The one single valid comment.
Even more shocking than 100% perfect performance so far is this: it claims to have caught over 800 spam comments. First of all, I’m shocked that there were that many coming here (though, I admit, I’m also a bit flattered). Second, I’m stunned that the simple keyword blacklist function in Wordpress was as effective as it was–cutting 800 in three days down to a dozen to thirty twice a week.
Third (and most importantly to anyone who reads this), I can now get rid of that obnoxious captcha on the comment form–the thing that forces you enter the scarmabled text from the generated image. SK2 will pop up a captcha for you to fill in if it has concerns about your being human, but it saves that for fallback purposes.
Captcha stands for “Completely Automated Process for Telling Computers and Humans Apart”, by the way. That’s the technical term for those scarmabled text “I’m actually a person” thingies. It’s a proper acronym, like Scuba, not an initialism like NASA or The FBI.
