I'm thinking along the lines of "let's ban all the Chinese" and "let's ban all the Russians", because that's where the abuse comes from. That's often what those models, both simple and advanced, boil down to.
American stores could prevent most shoplifting by banning people of a certain skin color from entering. The US doesn't let them do this, even though it would most definitely work. They're not allowed to do it for a very good reason, but those reasons seem to be lost to internet companies, who seemingly push so hard for diversity, equity and inclusion.
