This is the big thing.
You don't have to "prove" that it's made with AI or whatever.
You can just reject with "sorry, this doesn't look right to me, I don't feel comfortable engaging with this". You *may* choose to engage in some education, but you cannot be required to do so no matter what.
Anyone who insists you have an obligation towards them, other than being decent and suitably polite, automatically disqualifies themselves.
