Do you want to determine that a user is a bot almost all of the time, assuming people are not trying to fool you?
It would be nice to be able to do that, but it doesn't seem like it would solve any problems that we actually have. Would it?
But sure, if you want to code it up, I think it makes sense. If we heuristically detect that someone is "acting like a robot" then on the fly, we stop and ask them: "are you a person or a robot" with images such that only a person could answer properly. If they fail the test, we classify them as a bot.
