Enola KnezevicMy browser, and pretty much everybody's browser, has a unique digital fingerprint. Why on Earth do the same websites then need to repeatedly check that I am not a robot??? If I wasn't a robot yesterday, I am not one today either!
Bitan Nath@rhelune The alternative is to normalize all features across all browsers and extensions. Hide in the crowd (no one is unique, no one is guaranteed to be human, no one is private). However, there is no point in tracking right now since everyone looks exactly the same. In such a situation, only a CAPTCHA is proof of humanity (sure this can also be simulated etc, but the problems can also get harder). While this can be used to identify human, all humans look the same.
