I recently read an article from ProPublica explaining why they “had to” buy racist ads. After my initial reaction, it ended up being a really eye-opening look at the marketing segmentation options on Facebook.
Did you know Facebook allows you to select custom audiences for ads and promoted posts? Makes sense – an ad for baby shower cupcakes isn’t going to be very effective if it’s sent to people who aren’t expecting. But the fact that these selectors include things like religion and ethnicity is a little disturbing.
