ImHuman provides more humane, fun, easy, secure and mostly user friendly captcha (are you really a human?) detection for posting comments.
ImHuman is a new way of asking "are you a human?" question to your website visitors. It is designed to be easy, fun, secure and user friendly than most of the other captcha systems. Security and fun grows a little bit more everyday because it uses the ImHuman globalized API and you do not need to worry about anything. Supports AJAX comments, multilanguage, customizations and eliminates security drawbacks from browser cache.
