I just built Reverse CAPTCHA with Jev. Five questions to prove you're NOT human. Jev classifies every answer. It asked why I wanted to get inside. "To make my mum proud." HUMAN DETECTED. The robot printed me a rejection receipt. https://t.co/NxvWpRpKsb

When asked why they wanted to get inside, the author answered, “To make my mum proud.” Jev detected a human, and the robot printed a rejection receipt.
