Anyone without a badge can be assumed to be unvacinated.
Let's use AIDS for example, they make a badge that is certified AIDS free and then offer free AIDS testing then you can assume anyone without the badge has AIDS.
This is a hipaa violation by publishing some users information that has approval and waivers you are exposing the other users information.
Going with this example, let's say you have a group of people who voted wrong and you want to punish them, you don't let them display the AIDS free badge. It is an abuse vector.
Here is one recent one who wasn't doing it for profit: https://en.m.wikipedia.org/wiki/Austin_serial_bombings he wasn't killed by the police (directly) and he killed some people. The story of Dagobert wouldn't be as amusing if people died, but he did hurt people and caused psychological harm. Real people worked in those stores and other stores like them. The legal system has very little to do with justice, but I have no sympathy for someone placing explosives and hurting people, no matter the remorse.

Once I had to solve a memory problem because someone assigned what should have been a byte array to a list of byte. Nice enough programmer for high level concepts but needed the fundamentals. I think a good skills assessment is needed and then you patch the missing knowledge. A smart resource who can learn and is nice to work with is still a good hire.
