<p>Multi-Form Anti-Spam Image CAPTCHA adds a fast, accessible icon challenge — paired with honeypots and a submission speed check — to the form plugins and WordPress core screens spambots love to abuse. Users select the requested icon to verify; every challenge is generated server-side with a hashed answer so bots cannot scrape the correct option from the markup.</p>
<p>One plugin covers Gravity Forms, Contact Form 7, WPForms, WooCommerce, WordPress login, comments, and more — with full styling controls, 780+ icons, and layered bot defenses.</p>

<h4>Developer hooks</h4>
<ul>
<li><code>pbmfasic_skip_wp_login_option</code> — filter whether validation runs on WordPress login, registration, lost-password and reset-password forms</li>
<li><code>pbmfasic_skip_validation</code> — filter whether validation should be skipped for the current request</li>
<li><code>pbmfasic_force_synchronous_render</code> — return true to render the CAPTCHA inline instead of lazy-loading it via AJAX, useful when a form submits over a custom AJAX flow that needs the CAPTCHA fields present at first paint</li>
</ul>

WP-Biz (Ryan)

<p>The “honeypot” technique for SPAM protection is invisible to humans, and tricks robots into filling out an invisible form field. Then, if that invisible field has been filled, the form cannot be submitted. Easy, non-instrusive SPAM protection.</p>
<p>No settings to set, this honeypot is added to all Formidable forms on your site, unless the user is logged in. When SPAM is suspected, the form will not be submitted and the visitor will be alerted to this fact.</p>
<p>Tested to work with both <strong>Formidable</strong> (free) and <a href="http://www.wpbiz.co/go/forms" rel="nofollow ugc">Formidable Pro</a> (best bet for awesome form power!)</p>
<p><strong>A note to Formidable Pro users:</strong> You paid to receive extra features in the Formidable plugin. Me too, it’s well worth it. This Honeypot plugin, and Ryan (the developer) are not connected to Formidable in any way. Since this adds another very helpful feature to Formidable, I ask you to send a <a href="http://wpbiz.co/donate/" rel="nofollow ugc">donation at WPbiz.co</a> to say thanks and encourage future developemnt.</p>
