I've run across a desktop application called FotoJet Photo Editor at Mac App Store. It's a brand-new application. So it's been around for just several hours. There's already a positive comment with 5 stars. (If you don't see it, switch the country to the U.S. market.) That raises my suspicion. The name of the person making the comment is Phoebe.buffay. If you look at the comment history, this person has made three comments. They are made about the products created by the same software developer with 5 stars. Obviously, these reviews are fake.
What can we do about it? We lose more and more priviledges because of those who violate rules.
