Facebook Statement on Discriminatory Rental Ads Purchased by ProPublica This was a failure in our enforcement and we’re disappointed that we fell short of our commitments. Earlier this year, we added additional safeguards to protect against the abuse of our multicultural affinity tools to facilitate discrimination in housing, credit and employment. The rental housing ads purchased by ProPublica should have but did not trigger the extra review and certifications we put in place due to a technical failure. Our safeguards, including additional human reviewers and machine learning systems have successfully flagged millions of ads and their effectiveness has improved over time. Tens of thousands of advertisers have confirmed compliance with our tighter restrictions, including that they follow all applicable laws. We don’t want Facebook to be used for discrimination and will continue to strengthen our policies, hire more ad reviewers, and refine machine learning tools to help detect violations. Our systems continue to improve but we can do better. While we currently require compliance notifications of advertisers that seek to place ads for housing, employment, and credit opportunities, we will extend this requirement to ALL advertisers who choose to exclude some users from seeing their ads on Facebook to also confirm their compliance with our antidiscrimination policies – and the law. -- Ami Vora, VP Product Management, Facebook
