This silly solution is often suggested by tech bros who have a really rudimentary understanding of social problems. I guess it makes sense to someone who doesn’t fully understand social issues and thinks of how they would solve it if it was a technical problem. It’s not. Anonymizing does not reduce discrimination. It demonstrably makes it worse. The only things that do reduce discrimination in the short term is rules that deliberately relatively advantages the discriminated class and in the long term, socio-cultural shift.
