Google reCAPTCHA is service that protects your website from spam and abuse. reCAPTCHA engages users through a screening activity every time they sign up or fill out dynamic contact forms. This prevents automated software from performing abusive activities on your site. While it keeps your site spam-free, the screening activities allow users to pass through with ease.
