Facebook has a policy where they can arbitrarily ban you for failing to "prove your identity" if they believe your account does not use "the name you go by in real life." One of the ways they ask you to prove your identity is to send in a license.

Unsurprisingly, this ends up hurting all sorts of people who do not use their legal names online: people who have just chosen other names, people who want to avoid being targeted or stalked, trans people, etc. They've updated this policy to allow for some of these situations (https://www.cbc.ca/news/technology/facebook-real-names-1.336...) but folks still get banned for failing to comply.

As soon as someone manages to get your account flagged as possibly using a fake name I think.

If that is the case it would be harder to get a FB account than to vote in some states...
