> A few years ago, intentionally fingerprinting or tracking your users without disclosure was spyware and unethical. Alas, here we are.
For over 15 years reCAPTCHA has relied on browser fingerprinting to help distinguish humans from bots. And fingerprintjs.com has been around for well more than a couple years.
That said, sniffing the browser extensions someone is using is NOT a common fingerprinting method used by my examples, but just saying fingerprinting itself without explicit disclosure has been around for quite a long time. It happens on literally every CAPTCHA service. I hate it of course, but the ship sailed a long time ago.

I like this demo for testing my browser's resilence against fingerprinting: https://fingerprint.com/demo/
