I don't get the part about the reverse number lookup. Couldn't they be using a disposable phone number that is allocated to Facebook? That's what Handy, Airbnb, Uber, etc. do. Why would they have to block their caller id? And how does either method prove or disprove that M is human?

That doesn't prove that M's human, what prove's it's human is that a Human voice called. The fact it says Facebook is just evidence that it was indeed from M, and not just him getting his friend to call him and pretend.

It doesn't really prove anything, since caller ID is extremely easy to spoof (I used to call my mates from the emergency number for kicks when I was younger). Not that I have any doubt as to the credibility of the story.
