How this module works
The module adds a text field to the form that is hidden with CSS. This technique is called honeypot. Visitors do not see the field and leave it empty. Spam robots do not look at the page like a person, they fill in every field they find. If the hidden field contains text, the form was sent by a robot.
In addition, the module measures how long it took to fill in the form. People need a few seconds, robots send the form at once.
Protected forms
- News Script, Guestbook Script and Comment Script: the comment form
- Short URL Script: the form for new short URLs
- Disposable E-mail Script: the forms for new addresses and for replies
Settings
- Minimum time to fill in the form: 3 seconds by default, 0 switches this check off
- Mode: off, moderate or reject. New disposable addresses are always refused.
