The U.S. Department of Housing and Urban Development (HUD) has filed a formal complaint against Facebook for violating the Fair Housing Act due to the social media giant providing tools to landlords and home sellers that allow them to actively discriminate against protected classes. Facebook tools allow targeted advertising so a landlord or home seller can choose to discriminate by excluding who can see their ad due to factors such as the recipient's race, color, religion, sex, familial status, national origin, disability, and/or zip code. Facebook promotes these features as "success stories" for finding "the perfect homeowners," "reaching home buyers," "attracting renters" and "personalizing property ads." "The Fair Housing Act prohibits housing discrimination including those who might limit or deny housing options with a click of a mouse," said Anna María Farias, HUD's Assistant Secretary for Fair Housing and Equal Opportunity. "When Facebook uses the vast amount of personal data it collects to help advertisers to discriminate, it's the same as slamming the door in someone's face."
