## Description

Adds a hidden field to comment forms, which will subsequently be auto-filled by 
spam-submitting robots. If the form
 submission contains a value, the comment will
not be saved, because only robots will see the field and fill it out.

Simple!

Any form which is processed using the hook `comment_form_after_fields` (building
the form HTML) and `preprocess_comment`
 (for processing the form submission) will
be extended with this functionality.

This plugin doesn’t block or catch any form submissions which have been filled manually
in a browser, so you may still
 receive the occasional advertising or sales message
as a post or page comment. However, blocking automatically-generated spam messages
will reduce the number of unwanted messages greatly.

## Installation

 1. Upload the plugin folder to the `/wp-content/plugins/` directory
 2. Activate the plugin through the ‘Plugins’ menu in WordPress
 3. That’s it.
