Is the checkbox captcha "I am no robot" effective?

By codenovae September 08, 2018

I have seen a captcha relative often which only shows a checkbox with the text "I am no robot". A click on it and the form will be saved. Does anybody know how effective this spam protection method is? I think it is really user-friendly. Does Drupal 7 support this kind of captcha? Does a module exist to implement this easy capture?

This is the dedicated module for reCAPTCHA

By Skywalker September 08, 2018

This kind of CAPTCHA is really user friendly. And certainly there is a dedicated module to use it on Drupal 7. reCAPTCHA is a module which uses Google's web servicef for better CAPTCHA system. It lets human visitor a easy pass.

Yes ok, but I would also like to know how effective this kind of captcha is. Can this kind of captcha exclude bots to 100℅?

I wouldn't say it is 100% bot preventive

By Codemaster September 08, 2018

Every security system has its flaw. Bots can bypass reCAPTCHA using a method known as  clickjacking or UI redessing. To bypass bots may use a site's data key or public key which they want to access and disable another site's refer header and ask a user from the second site to solve the reCAPTCHA for them. Then this solved response may be used by the bots.

I think you got my point.
