I am getting a lot of comment spams lately. It was reallly getting into my nerves, with message like “Hey, I bumped into your site, bla.bla.bla.” with tons of hyperlinks added behind. So I decided to install captcha, a simple feature that helps to tell computer and human apart. It is a distorted legible image of randomly generated text that you need to enter when you submit a form.

I know it is irritating for the extra step but I just need to tell if you are a computer or a human. I am using Captcha!, a plugin for Wordpress.
