For more information & developer documentation, see the plugin’s website.

Does WordPress Zero Spam check Ninja Forms submissions?

No. As of v4.10.0, WordPress Zero Spam no longer checks Ninja Form submissions. Support was dropped due its requirement of JavaScript and how it submits forms. JavaScript is one of the techniques WordPress Zero Spam uses to determine if a submission is spam. Ninja Forms employs a similar method and has its own spam detection feature.

Does WordPress Zero Spam check Jetpack comments?

No. WordPress Zero Spam is unable to integrate Jetpack. For more information, see https://wordpress.org/support/topic/incompatible-with-jetpack-comments.

Spam coments are still getting through, help!

WordPress Zero Spam relies on the default core form id (#commentform) in order to check comment submissions. Verify your comment forms have this ID or add the class wpzerospam to enable it on your site.

All registrations are marked as spam, help!

This is most likely due to a plugin or theme overriding the default markup of the registration form. Verify the form has an id of registerform or add the wpzerospam class to it.

Example with registerform id:

<form name="registerform" id="registerform" action="https://yourdomain.local/login/?action=register" method="post" novalidate="novalidate">

Example with wpzerospam class:

<form name="registerform" class="wpzerospam" action="https://yourdomain.local/login/?action=register" method="post" novalidate="novalidate">

If you need help, please don’t hesitate to reach out.

How do I integrate this into another plugin or theme?

It’s easy as adding the class wpzerospam to the form element, then adding a check in the form processor that the wpzerospam_key post value matches the option value in the database using the wpzerospam_key_check() helper function. See the plugin’s documentation for more information on available hooks & functions.

Is JavaScript required to check form submissions?

Yes. One of the many techniques WordPress Zero Spam employs requires JavaScript be enabled to work properly.

Does WordPress Zero Spam use cookies?

Yes. It does not store any kind of personally identifiable information. Only one cookie is stored (wpzerospam_api_blacklist) to log the last time the site queried the blacklist APIs. This is used to boost performance so each page visit doesn’t trigger an API call. The expiration can be set in Admin > WP Zero Spam > Settings
