If you read some of the linked documents, they admit that their process isn't currently perfect and are working on finding better ways of verifying identity without depending on government IDs.

...and in the mean time their current process continues to shut down the accounts of people who are using their "authentic" names but don't have proper documentation. It's disingenuous for them to be calling this an "authentic name" policy when they have no intention of enforcing it as such.

People have been complaining about this for years and FB has yet to actually change their policy. This is a company that has "Move fast and break things" as a motto, and you expect us to believe that they cannot move fast with updating a company policy doc?
