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?

    I have two guesses:

    1. Low bar just checks that it gets clicked.
    2. Script on the pages watches mouse movements, etc., and bases its decision on that data.

      I’m pretty sure it’s just number 2.

      A program will click the box and hit submit instantly. Or it’d move in a perfectly straight line to either the centre of each or the edge of each and click as quickly as possible.

      Real human movements are not as precise.

          Remember, it’s not about filtering out robots, it’s about filtering out dangerous (as in spam, malware, etc.) things.

          I mean, If you’re reeeeeeally good and reeeeeeally precise and reeeeally fast … then maybe you’re as dangerous as the robot. Maybe it’s just safer to keep you out. 🙃
