This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

Concise Antispam



  1. Plugin generates token on the backend side.
  2. Plugin adds hidden field for token in each form which will use method “POST” after rendering of the page.
  3. Plugin inserts token in the field after user’s interaction with site.

For developers

Antispam will automatically check submissions of the regular forms but ignores all AJAX requests.
If you want to change this behaviour, you can use filter concise_antispam_need_to_validate_token.
See example:

Disable Antispam for some forms:

add_filter("concise_antispam_need_to_validate_token", function($needToValidateToken) {
    if (!empty($_POST['do-not-check-antispam-token'])) {
        $needToValidateToken = false;

    return $needToValidateToken;

You can also always manually call \Concise\Antispam::validateTokenOrDie() in your custom handler.

Formidable Forms integration

For proper work disable the honeypot checking in the forms


  1. Upload plugin to plugins directory
  2. Active plugin through the “Plugins” menu in WordPress

Thank you so much for this plugin. I didn’t notice the email attack on my client’s web site until 490,000 messages had been blocked and quite a few had gotten through. The number was increasing by about 3000 per minute, and after enabling this plugin, the incoming messages were just STOPPED, INSTANTLY.

Works like a charm. It doesn’t slow down the page at all and catches all spam with incredible accuracy—I haven’t had to delete a single spammy message since installing it. Excellent work!
