The Strong Testimonials: Captcha extension protects your testimonial submission forms from spam and other types of automated abuse. You can add javascript honeypots or Google reCAPTCHA which uses advanced risk analysis techniques to tell humans and bots apart. Choose from multiple reCAPTCHA versions to better suit your site needs:

reCAPTCHA v2 (“I’m not a robot” Checkbox)
Strong Testimonials: Captcha 1

The “I’m not a robot” Checkbox requires the user to click a checkbox indicating the user is not a robot. This will either pass the user immediately (with No CAPTCHA) or challenge them to validate whether or not they are human. 

Invisible reCAPTCHA badge

The invisible reCAPTCHA badge does not require the user to click on a checkbox, instead it is invoked directly when the user clicks on an existing button on your site, in our case the `Submit` testimonial button. By default only the most suspicious traffic will be prompted to solve a captcha. To alter this behavior edit your site security preference under advanced settings in your Google Recaptcha Admin

reCAPTCHA v3

reCAPTCHA v3 allows you to verify if an interaction is legitimate without any user interaction. It is a pure JavaScript API returning a score (between 0 and 1). This score is based on interactions with your site: 1.0 is very likely a good interaction, 0.0 is very likely a bot, giving you the ability to stop the testimonial form submission if the user doesn’t pass this score.
