App Store reviews available for sale on the Fiverr marketplace
Apple has been intervening on a case-by-case basis for some time, though it is unclear when they began the push as it is not a publicly-announced process. The moves were first reported by TechCrunch.
The most recent developer to feel Apple's wrath was Daneco Ltd., makers of "spammy" app Better Fonts Free. The app was stripped of more than 15,000 fake reviews over night, a change that only Apple could implement.
According to the publication, Apple "often" intervenes when such trickery is discovered. Many fake reviewers are careless, taking little effort to cover their tracks and flooding the App Store with hundreds or thousands of 5-star reviews in a short time.
The practice of buying reviews has become more commonplace recently as fly-by-night developers look for a quick payday by getting their app to the top of the App Store sales charts. Such a position can be worth tens of thousands of dollars in earnings each day.
