I don't know enough about your legal system to be sure, but just as an option, wouldn't it be possible that the mere act of creating a my fake ID could become a felony, if it isn't already? Just like the act of defacing your currency is illegal, even if you don't pay with that money. For me, the safest verification is what I had to do for my first email address in Germany, which is that the postman comes to your house and verifies that you are who you claim to be. Alternatively, and pretty much equally secure, our passports include the option of digitally verifying your identity at home. However, I'm not willing to do either that for Facebook, the last option is probably not possible with US passports, and the first option would be rather expensive.
