A few weeks ago, I decided to remove the Math Spam Protection from my comments form, and opted to finally give Akismet a try again.
I had enabled it a long time ago, when I first began blogging, but found that a lot of good comments were being caught in the spam filter. So I disabled it, and went with the simplest captcha I could find. Unfortunately, captchas cannot do anything about trackback spam, of which I was receiving about 100+ per day.
So now, I finally have the freedom from the horrible amount of spam I was receiving. But I do have some commentators who are always being filtered into the spam folder, no matter how many times I approve them and they are marked as “false positives” in the system. And it’s not just new commentators either – some of them have been commenting on this site for months now, and are far from ever being considered spammers, and yet, there they are, caught in my Akismet spam filter.
