I know a lot of sites now use browser fingerprinting and the like in order to determine how likely a user is to be a bot. The modern web tracks a lot of information about users, and all of that can be used to gauge how ‘human’ the user is, though this does raise some other concerns. A sufficiently stalkerish site already knows if you’re human or not.

This CGP Grey video is great, and covers how many captchas are often used to train the bots. https://www.youtube.com/watch?v=R9OHn5ZF4Uo
