Agreed.

The only time I've submitted government ID online was for banking sites where it's only online sign up. I am OK with this because I understand this is a requirement set by the same government issuing the IDs with rules around how it can be used.

Social media sites have no such requirement. They have no such rules around the collection of this information. They can do whatever they want with it once collected. Privacy policies aren't enough. They can shift on a whim.
