I've been thinking about this for days. I see of no verifiable way to confirm a human does not post where a bot may.

The core issue is a human solving the captcha presented by enslaving a bot merely to solve the captcha, then forwarding what the human wants to post.

But we can make it difficult, not impossible, for a human to be involved. Embedded instructions in the captcha to try and unchain any slaved bots, quick responses to complex instructions... a Reverse-Turning test is not trivial.

Just thinking out loud. The idea is intriguing, dangerous, stupid, crazy. And potentially brilliant for | safeguard development | sentience detection | studying emergent behavior... But if and only if it works as advertised (bots only). Which is what I think is an insanely hard problem.
