Cool, so let's go to my next point. What mechanism do we use to prevent social media apps from the harm they do with minors if we cannot confirm which users are minors?

This seems like a huge lawsuit for the third-party who retained ID images that they no longer had reason to keep. I am not particularly trustful of corporations but they do have a vested interest in not making themselves vulnerable to lawsuits. This company probably is going out of business.
