Off-topic: this discussion reminds me a bit of what happened about five years ago when I offered to host a reddit AMA about anesthesia and anesthesiology and related subjects (I was board-certified in 1980).
The moderator asked me for proof that I was who I was, so I had to spend a couple days digging through my files to find my medical school diploma, board-certification document, medical licenses, etc., then scan and email them to reddit.
I did all that, and they said it wasn't sufficient proof: I needed to take a selfie with the documents and my driver's license to "prove" my bona fides.

At that point I said WTF? and bagged it.
No good deed goes unpunished.
