Facebook Lets Advertisers Exclude Users by Race — ProPublica

Imagine if, during the Jim Crow era, a newspaper offered advertisers the option of placing ads only in copies that went to white readers.
That’s basically what Facebook is doing nowadays.
The ubiquitous social network not only allows advertisers to target users by their interests or background, it also gives advertisers the ability to exclude specific groups it calls “Ethnic Affinities.” Ads that exclude people based on race, gender and other sensitive factors are prohibited by federal law in housing and employment.

Imagine if, during the Jim Crow era, a newspaper offered advertisers the option of placing ads only in copies that went to white readers.
That’s basically what Facebook is doing nowadays.
The ubiquitous social network not only allows advertisers to target users by their interests or background, it also gives advertisers the ability to exclude specific groups it calls “Ethnic Affinities.” Ads that exclude people based on race, gender and other sensitive factors are prohibited by federal law in housing and employment.
Here is a screenshot of an ad we purchased in Facebook’s housing categories via the company’s advertising portal:
The ad we purchased was targeted to Facebook members who were house hunting and excluded anyone with an “affinity” for African-American, Asian-American or Hispanic people. (Here’s the ad itself.)
When we showed Facebook’s racial exclusion options to a prominent civil rights lawyer John Relman, he gasped and said, “This is horrifying. This is massively illegal. This is about as blatant a violation of the federal Fair Housing Act as one can find.”
La réponse “langue de bois en béton” de Facebook :
Facebook says its policies prohibit advertisers from using the targeting options for discrimination, harassment, disparagement or predatory advertising practices.
“We take a strong stand against advertisers misusing our platform: Our policies prohibit using our targeting options to discriminate, and they require compliance with the law,” said Steve Satterfield, privacy and public policy manager at Facebook. “We take prompt enforcement action when we determine that ads violate our policies."
Satterfield said it’s important for advertisers to have the ability to both include and exclude groups as they test how their marketing performs. For instance, he said, an advertiser “might run one campaign in English that excludes the Hispanic affinity group to see how well the campaign performs against running that ad campaign in Spanish. This is a common practice in the industry.”
He said Facebook began offering the “Ethnic Affinity” categories within the past two years as part of a “multicultural advertising” effort.
La réponse sur le sens à donner à “Ethnic affinity” est intéressante, en ce qu’elle ne s’appuie pas sur une déclaration d’origine ethnique, mais sur l’analyse des affinités (amitiés + comportement), ce que le média social sait très bien faire tout seul.
Satterfield added that the “Ethnic Affinity” is not the same as race — which Facebook does not ask its members about. Facebook assigns members an “Ethnic Affinity” based on pages and posts they have liked or engaged with on Facebook.
When we asked why “Ethnic Affinity” was included in the “Demographics” category of its ad-targeting tool if it’s not a representation of demographics, Facebook responded that it plans to move “Ethnic Affinity” to another section.
Bon, l’article date de 2016... voir si c’est encore d’actualité. Mais le processus est intéressant à suivre.
