Too Long; Didn't Read
Facebook announced a change to its ad targeting system last year. The Markup found that such ad targeting is very much still available on Facebook’s platform. Facebook hasn’t explained how it determines what advertising options are “sensitive” and, in response to questions, declined to detail how it makes those determinations. The company has faced blowback for offering advertisers “interest” categories that speak to more fundamental—and sometimes highly personal—details about a user's interests.
