|Detail Plugin Description||
yaCAPTCHA is a CAPTCHA plugin for WordPress that helps you block comment spam from automated bots. In order to post comments, users will have to write down the characters that are part of an image. Since it is relatively hard for automated programs to figure out those characters, this will help prevent comment spam from those programs.
