Actually, that's not at ALL why I wrote that. I wrote that because I found it hard to not wonder if the two things were connected. Suddenly, user names are becoming @facebook.com email addresses.
I also wrote this line before Facebook ever responded to our questions (which they did just a moment before posting) and didn't remove it. Before the explanation, Boy Genius Report was speculating that it was a hack because of the request for a government ID. A quick Google search showed that a government ID request seemed to be a standard thing when Facebook wants to reactivate certain accounts, so I figured that wasn't the case and postulated that perhaps it had to do with Facebooks latest change...its messaging system.
The only reason I ever put links into a story is so that if you don't know about that, and it's readily accessible, you don't need to search for it. :)
