CAPTCHA
wundo - June 9, 2004 - 18:31
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. The administration settings for CAPTCHA are available at admin/user/captcha.

Alternatives
One of the disadvantages of using CAPTCHAs is that you can drive away legitimate users. You could also consider spam filtering or hybrid solutions like:
- The Mollom module, which only presents a CAPTCHA if the user input (e.g. a comment) looks like spam.
- The Akismet module (unsupported since the rise of Mollom)
- The spam module provides spam filtering and related tools
