look, even if hypothetically I was willing to scan my face and give a video of me to a social media company's shady unnamed third party data processor to do [God] knows what with in order to prove my adulthood...
chances are I can't. my body is that of a disabled Asian woman.
the facial markers of childhood on a white person- prominent monolid eyes, round faces without prominent cheekbones, clear, smooth skin devoid of wrinkles, lack of facial hair- are traits that many adults of Asian descent, many in their fifties and sixties even, have to an extent that several of my (adult, mind you) relatives and friends have been declared to be in their teens, or even to be preteens or 8-year-olds, by an algorithm that associated those features with childhood rather than ethnicity and lineage.
I can usually figure out how to look directly at a camera, if I try hard enough. but from what I've seen of Roblox's face verification process, it also needs you to move your eyes slowly from left to right so it can determine you're using live footage of a real person.
simple, right? wrong. I can't do that. I can kind of move my eyes a short distance(and it always hurts like hell, especially when I do it consciously), and I can change what part of my vision I'm paying attention to, but otherwise my only way to change what I'm looking at is to turn my entire head. and it clearly doesn't accept head-turning as "looking from left to right".
I don't have any other facial differences that might mess with the algorithm recognizing my face as a face- and that's a related problem that's already been documented by numerous people and organizations like Face Equality International.
I just can't follow the instructions, because it wants me to do something I can't do and expects that all adult humans can move their eyes consciously, because ha ha who couldn't do that if they're using a computer in the first place? it's not like disabled people might ever have friends or want to be on social media!
