RE: Facebook and LinkedIn, they're specifically not verified information. I could sign up to Facebook under a fake name, with fake details, and though it'd probably get me banned from Facebook once they got around to it, it's very much not impossible. A Facebook account takes slightly more time to fake than lying about a date, but that's the only barrier. It is not any kind of trustworthy identifier (unless you have access to the decentralised data aggregation that such sites actually make money off, but that's another tangent).
People are saying actual ID is a big deal because it is. If you'd be happy to accept the level of security a Facebook account would offer, you could ask people to link to an active Twitter, Tumblr or other social media with their age somewhere on it. That's a less-invasive method other fandom spaces use.
