To prevent our site being spammed, I've enabled captcha during registration of new users. Captcha is "a type of challenge-response test used in computing to determine whether the user is human."

In our case, if you're a new user, you will be asked to solve a simple math problem during registration. I hope this first line of defense against spam bots  will work so that I won't have to enable captcha during posting of content. Just e-mail me at pinoytechie.com at gmail dot com if you encounter any problem.
