Facebook already has a good mechanism for validating account owners which involves showing users random unlabeled photos of their friends and asking them to guess who's who.

I guess an excuse like "you got hacked" helps you get much more important information from your users.

No one is talking about how all of the sudden, a lot of accounts supposedly got "hacked".

How on earth could this "solution" to trick its users possibly scale to more than 1 billion active accounts?

Don't get me wrong, I absolutely believe that Facebook would like to link government IDs to each and every account if they could, but trying something like this would be the end of Facebook.

They can't be that stupid.
