CAPTCHAs don't prove you're human – they prove you're American (2017)

At this point I assume the captcha puzzle isn’t the actual check, just a distraction while they fingerprint your browser and behaviour to try to identify if you are more likely a human or not. Just my thoughts, I have absolutely no proof that’s the case, but I don’t believe labeling traffic light is still valuable, we are way, way past that

  The big sell on reCAPTCHA v3 was that it did all the fingerprinting beforehand. Only when fingerprinting failed to prove your humanity, you'd get shown a puzzle.
  I've tried intentionally answering the prompts wrong and correctness is definitely a factor here (although low bot scores seem to permit you more mistakes). That doesn't mean fingerprinting is not happening while you're solving the puzzles, but it's more than just a distraction.
