They wanted to scan my face, and in a moment of weakness, I performed the ritual. Thirty seconds later, they suspended my account due to violations of their terms of service: "this decision cannot be appealed". So now they have my face and I still can't use the marketplace.
I can only assume I'm suspended due to the behavior of somebody who tried to use my identity for something during the decade when I had no facebook account. Apparently not even my face is strong enough authentication for me to convince them that I'm not whoever it was that caused whatever the problem was.
This is why biometrics will never make sense. They're too immutable. Maintaining multiple accounts is not a bug, it's a debugging mechanism. Since I have only the face that I do, I can't even figure out why I'm banned.
We need to instead stop trusting people merely because they have an account. 10k upvotes/likes/5-star-reviews should mean nothing if I don't explicitly or transitively trust the upvoters/likers/reviewers. We have to build things that make decisions by traversing the trust graph so instead of being banned with no recourse, I can create a no-trust identity and elevate it back to personhood status by convincing my meatspace friends to trust it by having a conversation with them in meatspace.
