The Spamicide module protects Drupal forms with a form field that is hidden from normal users, but visible to spam bots.
The module doesn't require appropriate permissions for administrative pages leading to an Access Bypass.
Install the latest version:
- If you use the spamicide module for Drupal 7.x, upgrade to spamicide 7.x-1.3
Also see the Spamicide project page.
