I have noticed that some CAPTCHA pages, like Cloudflare’s, simply ask you to check a box to proceed. There is no clicking on traffic lights or entering characters. How does clicking on a check box tell them I am not a robot?

Big part of the internet is going through Cloudflare these days, so it tracks you as you browse, and does something clever to figure out if you’re a robot. Google can do the same, they’ll have a cookie on you. If they’re not sure they’ll show you one of those challenges.
