There's an unmet need in social networks for "identity verified and protected", wherein the social network proves to a reasonable^ degree of certainty that you are who you say you are, and then you are permitted to maintain an anonymous identity (which you may end and replace with a new one at any time). ^ Notarization, at $25/each, would be sufficient. Bank account verification and credit card verification would not be sufficient, nor would "upload a photo of your ID". There's no sidestepping the "human being evaluates your actual identity documents" stage.
