| Do you consider that a CAPTCHA? Yes:"Completely Automated Public Turing test to tell Computers and Humans Apart"

But funny enough, I believe that data is used to help with machine learning to identify the objects, so we are CAPTCHA'ng ourselves into harder and harder CAPTCHA's.

The "I am not a robot" types are interesting because they don't just test you, they monitor your behavior. "If it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck."
