Facebook Ads Aren't Working for Christian Authors

Facebook ads allow you to target fans of similar authors, unless you write religious books that is. So Facebook discriminates against religious authors, preventing them from targeting readers of religious books. Another strike against Facebook ads is that with the recent privacy changes on the iPhone, the ads don't work as well even for secular authors. As people are leaving Facebook, and users that it does have are spending less time on Facebook, the ad inventory is shrinking.
