Description
RUH Captcha is a WordPress plugin that helps
filtering out all robot attempts to register/comment.
A human being can identify easily (after a few moments of thinking, of course) two closest matching objects from nine. Standard version comes with a static set of pictures, stored in my database. Customization is possible, please contact me if you are interested. Also, some security improvement may be added.
For more information, check out RUH.
