That's called authentication. In the case of the stalker, by biometrics (facial recognition). This could be a solution

But that's not what Cloudflare does. Cloudflare guesses whether you are a bot and then either blocks you or not. If it currently likes you, bless your luck

Until the moment someone will figure out the generation of realistic enough 3d faces.

		Ah true! I meant authentication in general by whatever means, which seems dystopian enough already, but indeed my post can be read as being about facial recognition being required to visit random websites... that's even worse! Don't give them ideas xD
