«Facebook is bringing « dark posts » into the light in response to the election interference on social media last year, and the new rules will impact all advertisers.On Friday, Facebook revealed a new system of disclosing what groups and companies paid for ads on its platform: Any ads running on Facebook will be readily viewable by anyone.That means no more so-called dark posts, ads that target only a particular set of people but are invisible otherwise because they never appear as posts on a brand or group’s page».
