Facebook disables ethnicity advert targeting system
Facebook has temporarily turned off a system that let advertisers choose which ethnic and minority groups saw their ads. Facebook does not explicitly ask its users to declare their ethnicity, but it typically infers someone's ethnic group from their activity on the social network. When the targeting was first uncovered, Facebook said it would find a way to spot and block attempts to post discriminatory ads. In an earlier statement, Facebook said the ads placed by ProPublica had been approved because of a "Technical failure" in its enforcement system. Ms Vora said the discrimination-spotting system Facebook had created after ProPublica's first investigation had managed to spot millions of other ads that had broken its guidelines.
