Facebook Inc. is stepping up enforcement in its ad-targeting system and adding human reviewers to make sure that offensive categories aren’t an option, after a report by ProPublica showed that it was possible to target people who described themselves as “Jew haters.”
Chief Operating Officer Sheryl Sandberg said the social network will make reviews of its self-service advertising system more manual. Facebook will also clarify its advertising policy to disallow targeting using any criteria that directly attacks a group of people.
“We never intended or anticipated this functionality being used this way — and that is on us. And we did not find it ourselves — and that is also on us,” Sandberg said Wednesday in a post on Facebook.
