Is the checkbox captcha "I am no robot" effective?
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?
I wouldn't say it is 100% bot preventive

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.
