How do CAPTCHAs work without giving you a challenge task? - eviltoast

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?

    Yeah, that sounds reasonable. Touch input is reported similar to mouse input, so it would translate to a touch screen pretty well.
