Thank you for your reply. Just so you know I'm asking because I'm thinking about creating a youtube video about data collection and social media. I have a few more questions if you have time. Please, please, PLEASE cite sources for your answers. I realize that it's not legal advice and won't be taken that way but your answers here will help me create the video so the more information I have the better. Thank you.

Meta only asked for a pic of my face, nothing else.

Unless they ran the pic against some database, how would Meta know the photo I provided was even me?

Are Social media companies required to tell users how they're confirming the user-provided information? I assume that is something they would have done in the EULA I agreed to at sign up but the email I received informing me my account was suspended only linked their Community Standards.

If they don't have a way to conclusively prove it's me, why ask?

Why not simply compare the information I already provided against public records?

Let say I submitted my photo yesterday and today someone hacked Facebook and got my stuff. What would be recourse for me? Would Facebook be required to inform me of the breach? If not, why? If so, what other regulations must Facebook follow?

What about general PII collection and maintenance? Lets say I deleted my account right now, Other than an EULA, Are there laws governing how long Facebook can keep the information and what they can and cannot do with it?
