This plugin will manipulate the Jetpack <code>[contact-form]</code> shortcode to prepend the Google script, add a button, and parse the response.

reCAPTCHA for Jetpack enhances your WordPress site’s security by integrating Google reCAPTCHA v3—an invisible, score-based spam filter—with Jetpack contact forms and comments (including forums). Designed for block-based themes (e.g., Full Site Editing), it uses behavioral scoring to block bots seamlessly. Key features:
<ul>
<li>Invisible Protection: Analyzes user behavior (e.g., mouse movements, session duration) to assign a score (0.0–1.0) for contact forms and comment forms.</li>
<li>Customizable Threshold: Set a score threshold (default 0.5) to balance spam blocking and user access for both forms and comments.</li>
<li>Debug Mode: Toggle console.log output for debugging purposes; disable for production to reduce browser console clutter.</li>
<li>Automatic Spam Handling:
<ul>
<li>Form submissions with scores below the threshold are reliably blocked and moved to the Jetpack Feedback CPT spam folder in the admin interface.</li>
<li>Comments with scores below the threshold are automatically moved to the spam folder without triggering approval emails.</li>
</ul>
</li>
<li>Submission Stats: Tracks total submissions and logs the last 20 submissions (forms and comments) with scores and status (success/spam) in a streamlined manner.</li>
<li>Jetpack Integration: Requires Jetpack for contact form and comment protection, fully compatible with block-based forms and Jetpack forums.</li>
<li>Email Enhancements: Appends reCAPTCHA scores to form submission emails and comment notification/moderation emails for transparency.</li>
<li>Admin Feedback: Displays reCAPTCHA scores to admins on form success pages and logs detailed debug info for failed submissions.</li>
</ul>
Perfect for modern WordPress sites, this plugin provides robust spam prevention with insightful analytics, ensuring a seamless user experience while keeping your forms and comments spam-free.
<h3>External Services</h3>
This plugin uses Google reCAPTCHA v3, a service provided by Google to verify user interactions and prevent spam on contact forms and comments.
<ul>
<li>Purpose: Google reCAPTCHA v3 analyzes user behavior to assign a score (0.0–1.0) indicating the likelihood of a user being a bot. This score determines whether form submissions are blocked (moved to spam) or comments are flagged as spam.</li>
<li>Data Sent: When a user submits a form or comment, the plugin sends a reCAPTCHA token to Google’s API (<code>https://www.google.com/recaptcha/api/siteverify</code>). The request includes:
<ul>
<li>The reCAPTCHA secret key (configured in the plugin settings).</li>
<li>The reCAPTCHA response token generated by the client-side script.</li>
<li>The user’s IP address (optional, included for enhanced verification).</li>
</ul>
</li>
<li>When Data is Sent: Data is sent to Google’s API on every Jetpack contact form or comment submission.</li>
<li>Service Provider: Google LLC.</li>
<li>Terms of Service: https://www.google.com/recaptcha/about/</li>
<li>Privacy Policy: https://policies.google.com/privacy</li>
</ul>
Users must agree to Google’s terms of service when setting up reCAPTCHA keys. No user consent is required for reCAPTCHA v3, as it operates invisibly without challenges.
