Facebook has temporarily turned off a system that let advertisers choose which ethnic and minority groups saw their ads.
It said it would investigate how the feature was being used by advertisers.
News organisation ProPublica discovered that the system could be abused by posting discriminatory ads on the social network.
Facebook said it would look for a way to change the system so it could not be used “inappropriately”.
Last year, ProPublica first discovered the ethnic discrimination via advertising was possible.
US laws prohibit discrimination in the way ProPublica demonstrated – in adverts relating to housing, for example – was possible.
discriminatory ads that were not shown to people who were:
- interested in Islam
- part of other ethnic or minority groups
All the ads it submitted were approved.
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.
Facebook’s failure to do this raised questions about “its ability and commitment to police discriminatory advertising”, said ProPublica.
On Thursday, Facebook boss Sheryl Sandberg said it had now turned off the tools that let advertisers choose which “multicultural affinity segments” they wanted to reach.
