It is very strange that my post Function Overloading in PHP 5 brought many spam comments. I enabled Akismet plugin that has caught about 150 spam comments. However, somtimes Akismet can’t prevent all the spam comments and it just doesn’t allow the spam comments to show, the spams are still stored in the database.
Several days ago I read this article in Google Webmaster Central Blog. It shows some method to avoid comment spam. The first thing is using a captcha. Also, it gives a free script which is called “reCAPTCHA“. For WordPress users, reCAPTCHA provides a plugin, so that it is very easy to integrate with WordPress.
I don’t think the captcha code is a good solution to comment spam. It will make difficult to visitors who want to leave some meaningful comments. However, the comment spam is so serious, I have to do so.
