Liapes, a 46-year-old woman, alleged an actionable claim under the Unruh Civil Rights Act (Civ. Code 51.5, 51) for intentionally discriminating on the basis of gender and age in targeting (and allowing advertisers to target) their ads to particular audiences of Facebook users based on chosen characteristics, including age and gender.  She claimed that as a result of the ad targeting done manually by the advertisers or by Facebook’s automated algorithms, she did not receive ads for life insurance, a product that she was then searching for.  Targeting ads to an audience defined by immutable personal characteristics such as gender or age is intentional discrimination that violates the Unruh Act.  Furthermore, since Facebook knew advertisers were using those characteristics in selecting their target audiences and since Facebook implemented the advertisers’ decisions, Facebook could be held liable for aiding and abetting the advertisers’ Unruh Act violations.  Facebook was not immune as an  interactive computer service provider under section 230 of the Communications Decency Act because Facebook was responsible in part for the creation and development of the content that violates the Unruh Act.
