Add a hidden “honeypot” field to comment forms, to help combat comment spam.
As of April 2026, Simplest comment spam catcher is a WordPress form plugin with 10 active installations and a 0/5 rating0. It has been downloaded 1.9K+ times in total. Requires WordPress 4.0+ and PHP false+. Available on WordPress.org since 2016. Top alternative: MC4WP: Mailchimp for WordPress.
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.
