Facebook announced today that it would temporarily stop letting advertisers xclude users from seeing their ads based on race and ethnic group. The highly controversial (and legally dubious) practice was first uncovered during an investigation by Pro Publica in 2016. Though Facebook said it would end the practice when it came to ads for housing, credit or employment following the subsequent backlash, a Pro Publica report from just last week found that housing ads could still exclude black, Jewish and disabled users.
