2 of 5 measures had too little evidence to score. They are left out of the total rather than counted as zero — otherwise a plugin would be marked down for being small rather than for being poorly kept.Measured 2026-08-01 from the WordPress.org plugin registry.
Ratings

No one has rated this plugin on WordPress.org yet. That is a statement about the ratings page, not about the plugin — plenty of well-kept plugins never collect them.

Spam Defender – Review Captcha for WooCommerce helps you reduce spam product reviews by adding a captcha verification before review submission.

With this plugin, customers must solve a captcha before submitting a review, which ensures that only genuine users can leave feedback on your WooCommerce products.

Features:
* Support for both Google reCAPTCHA v2 and Cloudflare Turnstile.
* Adds captcha to WooCommerce product review forms.
* Blocks spam bots from auto-submitting fake reviews.
* Lightweight and easy to use.
* No coding knowledge required.
* Compatible with latest versions of WordPress and WooCommerce.

This plugin provides a simple but effective solution to keep your product reviews section clean and trustworthy.

External services

This plugin uses external services to protect the WooCommerce product review submission form from spam and automated bots. Depending on your configuration, it connects to one of the following:

Google reCAPTCHA

  1. Frontend Integration: It loads the reCAPTCHA JavaScript API from https://www.google.com/recaptcha/api.js on the product page to display the captcha challenge.
  2. Server-Side Verification: When a user submits a review, the plugin sends the reCAPTCHA response token to Google’s verification endpoint (https://www.google.com/recaptcha/api/siteverify) along with the Secret Key and the user’s IP address to confirm the validity of the captcha challenge.
  • Service: Google reCAPTCHA
  • Purpose: Spam and bot protection for WooCommerce product reviews.
  • Data Sent: Reviewer’s IP address and reCAPTCHA response token.
  • Terms of Service and Privacy Policy:
    • Google Terms of Service: https://policies.google.com/terms
    • Google Privacy Policy: https://policies.google.com/privacy

Cloudflare Turnstile

  1. Frontend Integration: It loads the Turnstile JavaScript API from https://challenges.cloudflare.com/turnstile/v0/api.js on the product page to render the Turnstile widget.
  2. Server-Side Verification: When a user submits a review, the plugin sends the Turnstile response token to Cloudflare’s verification endpoint (https://challenges.cloudflare.com/turnstile/v0/siteverify) along with the Secret Key and the user’s IP address to confirm the validity of the Turnstile challenge.
  • Service: Cloudflare Turnstile
  • Purpose: Privacy-friendly, non-intrusive spam and bot protection.
  • Data Sent: Reviewer’s IP address and Turnstile response token.
  • Terms of Service and Privacy Policy:
    • Cloudflare Privacy Policy: https://www.cloudflare.com/privacypolicy/
    • Cloudflare Website Terms: https://www.cloudflare.com/website-terms/

Does this work only with WooCommerce reviews?

Yes, this plugin specifically adds captcha to WooCommerce product review forms.

Do I need to configure anything?

Yes, once activated, you’ll need to select your captcha provider and enter your API credentials (Site Key and Secret Key) to complete the setup.

Is it compatible with other captcha plugins?

This plugin is specifically designed for WooCommerce product reviews. However, if you use another plugin for the same purpose, it may cause conflicts.

Will it affect site performance?

No, the plugin is lightweight and optimized for speed.
