Captcha: Are You Talking To A Human?

I’ve just got my first spam comment. That’s not a big problem for me, since I disabled HTML tags in my comment system, so they can’t post any real link in this post, nor a malicious javascript. It will be a problem in the long run though since I’m planning to add email notification to the comment system.

That’s why I immediately add captcha to the comment system. Captcha is a sequence of text which is printed on an image to make sure that only human can read and interpret it.

To understand how to make it, please visit this site (Indonesian). If you’re looking for an english alternative, you can google it. Just type “captcha php”.

Let’s fight spammers to assure our readers that they are talking to a human, not something else!
Happy blogging!
