What is reCAPTCHA?

reCAPTCHA was designed in 2009 to check that you are a real person and not a robot. It makes it possible to send your form securely, thereby preventing SPAM from being sent. One of the most popular extensions for contact forms is Contact Form 7, which has an add-on module that lets you add a CAPTCHA system to your form in just a few clicks.
