Add challenge-response tests to user-facing forms on your site to protect against spambot submissions. Other CAPTCHA types are supported via additional modules.

A CAPTCHA is a challenge-response test most often placed within web forms to determine whether the user is human. The purpose of CAPTCHA is to block form submissions by spambots, which are automated scripts that post spam content everywhere they can. The CAPTCHA module provides this feature to virtually any user facing web form on a Drupal site.
