If you want to avoid giving information about whether you are an AI or human, you simply respond "No."

Besides, the CAPTCHA's that are sufficiently hard to solve for computers are already hard for humans as well.

> Can you tag for me all photos in my album that contain a kitten, but not a dog, with "kitten", and those that contain a kitten and a dog, with "pets<3"?

That should keep it busy.

This approach is backwards. This is the kind of problem that is easy for a person, but not for an AI. So if M was an AI pretending to be a human, you could use this to determine that. But in this case, the suspicion is that M is a human pretending to be an AI - and they could simply decline to attempt the task, or pretend to be unable (or do a bad job deliberately), and you'd learn nothing from negative results.

Question isn't "will you?" -- it's "can you?"

"Yes, but I don't want to."
