Brands with fraudulent fans have a potentially significant handicap when it comes to organic reach. When a brand posts, Facebook trickles that post out initially to a tiny fraction of the brand audience. Based on those fans’ initial engagement with the post, Facebook determines post quality and what percentage of the brand’s full fan base to feature that post to. If 50 percent of fans are fake and never engage, the post will perform one-half as well as it should on the initial test run, and, therefore, suffer from low organic circulation, a very common gripe for brands.
