Facebook has been tight-lipped about what its unnamed friends list is, but it seems to be a powerful tool for the social media giant. The list is reportedly used to target ads and content to users’ friends, which could give Facebook an edge over its competitors. The unnamed friends list has been around for years, but it’s only recently come under scrutiny. In March, ProPublica reported that Facebook was using the list to manipulate users’ emotions. For example, if a user’s friend liked a post from a page with which they were feuding, Facebook would show that post to the user even if they hadn’t liked it themselves. Facebook has since denied these allegations and said that the unnamed friends list is only used to target ads and content that users might want to see. However, this explanation doesn’t seem to satisfy everyone. Some people believe that Facebook should be more transparent about what the unnamed friends list is and how it works. ..
