> One of the more insidious elements of ReCAPTCHA is its propensity to challenge users who have robust cookie blocking in place. It is understandable and I expect HCAPTCHA to do the same thing.
The goal of a CAPTCHA is to identify you as a human. I don't know how ReCAPTCHA works, but I expect it to be like spam filters: they have a sample of bots, a sample of humans and assign weights to every aspect, in the end, the algorithm spits out a probability of you being human, and it will challenge you until it reaches a set value. The thing is: if you hide everything for privacy reasons, you are making yourself indistinguishable from anything else using HTTP, including bots. That's the point, but it also means the only way to prove you are human is through a challenge. Think of it like a private club. If you a regular and the bouncer is likely to recognize you and let you in without asking anything. But if you don't want to show your face, you will need to show your membership card every single time. That's the price of anonymity. |
