Are these reviewed by a human? If so, why not 'just?' require the selfie to contain the document, some written nonce, and/or a weird body position, like a flag semaphore position?

I like the idea of asking to hold the same document in the selfie. Not a full-proof solution but way better than asking for any non-specific selfie.
