Block spammers by using No CAPTCHA reCAPTCHA by Google

You have probably come across CAPTCHA. It is a test that tries to differentiate human user from an application which is usually used for fighting spam. CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) usually puts a simple picture in front of you and makes you type the text from the picture (or one you hear) into a text box.

Although it was a very good technique for stopping spammers, there are applications able to find their way around this kind of security. Also, CAPTCHA can get very annoying for your visitors if they have to use it very often.

New solution for fighting spam and abuse comes from Google. No CAPTCHA reCAPCTHA is free service which easily tells humans apart from robots by using just one checkbox. When you finish your registration, log in or when you leave a comment, all you have to do is check the box and confirm you are not a robot. Of course, if you are a robot, please do not do that, everyone hates those kind of pretender robots!
