"....Last week, ProPublica bought dozens of rental housing ads on Facebook, but asked that they not be shown to certain categories of users, such as African Americans, mothers of high school kids, people interested in wheelchair ramps, Jews, expats from Argentina and Spanish speakers. All of these groups are protected under the federal Fair Housing Act, which makes it illegal to publish any advertisement with respect to the sale or rental of a dwelling that indicates any preference, limitation, or discrimination based on race, color, religion, sex, handicap, familial status, or national origin. Violators can face tens of thousands of dollars in fines. Every single ad was approved within minutes...." https://www.propublica.org/article/facebook-advertising-discrimination-housing-race-sex-national-origin

Seems it also doesn't apply if you are paying for an ad?
