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?

    I don’t think random websites get access to my browser history without me explicitly giving them permission.

      They pretty much do if they’re run through something like Cloudflare or they use Google Analytics. That probably covers about 80% of websites. Not the website, but the company that’s running the Captcha.

        Why do so many websites use cloudflare? Isn’t the Internet meant to be decentralised and resilient? It’s not so resilient if so much is dependent on the servers of one company.
