Thanks for extensive explanation, but idk how feasible and cost effective would be to do this "en masse". It seems like a lot of work and effort for small gain of cracking a captcha task/s. And yes I agree privacy would be a problem because people don't want some random and untrusted site to access their webcam and/or mic. But I still thinks my idea has some potential. Maybe someone else will come up with better captcha idea.
