<h3>External Services</h3>
This plugin uses Google reCAPTCHA v2 to help protect comment forms from automated spam.
When reCAPTCHA is enabled, the plugin loads the Google reCAPTCHA script from: 
https://www.google.com/recaptcha/api.js
When a comment form is submitted, the plugin sends the following data to Google for verification: 
• The reCAPTCHA response token 
• The user’s IP address 
• Your site’s secret key
This verification request is sent to: 
https://www.google.com/recaptcha/api/siteverify
