WordPress Zero Spam uses AI in combination with proven spam detection techniques and a database of known malicious IPs from around the world to detect and block unwanted visitors.

In addition, it integrates with other popular plugins to provide all-around protection. Just install, activate, and enjoy a spam-free site!

WordPress Zero Spam can be integrated into any form, plugin, or theme using its available hooks and helper functions. View the developer documentation below for more information.

Hi Ben,

I have raised a PR for Everest Forms to make it compatible. Please give a review regarding the PR raised:
https://github.com/bmarshall511/wordpress-zero-spam/pull/224

Thanks!

Thanks Shiva, I’ll take a look at it when I have a chance.

Hi Ben,

Thank you for all of your great work with this plugin.

With the new version 4.0.0, does the plugin still provide anti-spam protection for contact forms like Contact Form 7 and others?

Thanks again.

# Jul 15, 2020

Hey Dominic, glad you found it useful. 4.0.0 currently only supports comments & registration, but within the next day or two will have support all the 3rd-party plugin like CF7 that it did.

# Jul 15, 2020

WordPress Zero Spam 4.1.0 was just released & now includes support for all the plugins it did previously.

# Nov 27, 2019

The downside of this new plugin is that anyone without support for JavaScript will have their comments rejected. However, the percentage of actual commenters with JS turned off is likely to be infinitesimal compared to the number of bots trying to comment on your site. If you don t mind the JavaScript requirement and want a simple solution with no options to configure, then WordPress Zero Spam is a plugin that may work well for you.
