Though I applaud the effort to get age right and protect players, I'm not sure I'll ever be comfortable having me or my child scan our photo ID and selfie to upload it as part of a login flow to an application.
A component of my work is in digital identity, so I hope you don’t mind the question: what would make you comfortable doing so? For Roblox, I can see the exception taken, but some applications do require this level of identity proofing (scanning your passport in an airline mobile app to book an international flight comes to mind). Edit: Thank you everyone for your feedback, it’s very helpful!
Giving up that much PII for a game is insane. I'd uninstall it without even thinking. Any industry that's not regulated to require photo ID when they're asking for it doesn't need to ask for it.
