What is reCAPTCHA?

reCAPTCHA is a free service from Google that helps protect websites from spam and abuse. A “CAPTCHA” is a test to tell human and bots apart. It is easy for humans to solve, but hard for “bots” and other malicious software to figure out. By adding reCAPTCHA to a site, you can block automated software while helping your welcome users to enter with ease. Try it out at http://recaptcha.google.com/recaptcha/demo/.
