Facebook allows advertisers to target people based on insights gleaned from the vast amounts of personal information users input on the social network. In the past, this has enabled—as ProPublica first reported in 2016 and again in November of 2017—ads that exclude people based on race, which is illegal under federal housing and employment law.

Now, a group of fair housing advocacy organizations are suing Facebook on the grounds that leveraging user data to allow allegedly discriminatory ads is illegal, and Facebook is still doing it. The complaint is being led by the National Fair Housing Alliance (NFHA) and was filed in federal court in New York this week, where Facebook maintains an office.
