Why is anonymous @example.com email address created?

Hi wordmax,

The email field is required for WordPress comments. Although it’s allowed not to fill the email field from the frontend, the wpDiscuz adds some generated emails to avoid conflict with WordPress. This allows the comments to be published successfully.

Thanks. So I suppose that just using a [email protected] would not work just as well? Where “websitedomain” would be the domain where the site is installed.

This is done for finding differences between anonymous users. Otherwise, it’ll show as the same user made the comments.

The code below makes it work as you want:

add_filter('wpdiscuz_commenter_email', function($email){
    if(strpos($email,'@example.com')){
        $email = '[email protected]';
    }
    return $email;
});

Put the code in the active theme functions.php file.
