Not only that, but such a thing is probably illegal in the USA [0]. Someone needs to take it all the way through to the SCOTUS, although being forced to wear a scarlet letter as a form of public shaming has been ruled on before, if I understand correctly.
FWIW I can’t recall seeing one of these plates in 10+ years.
I have seen them before, though. Part of my family is a little, uh, rough, and when someone would get these in the past we’d say “oh so and so got their party tags”.
So I’ve always remembered them as party tags... lol.
