The platforms all seem to have a fallback "support a ticket with your government ID, and we pinky promise to delete the ID after verifying you".

But thats what this law does not allow according to the head of this chain, specifically government ids are not allowed to prove age, even if you delete them unless I read it wrong

Just telling you the options I was presented with, having to go through the process. I'm not sure what the alternative is for false positive identifaction as a minor.
