New evidence backs suspicions of Apple intervention
Apple is actively deleting reviews from the App Store that it believes to be fake, sources say. Less moral developers are believed to pay for positive reviews, sometimes in bulk, in order to push an app higher in the App Store's charts and thus pick up more sales. Apple has allegedly been cracking down on fake ratings for a period of time, but until now evidence was relatively scarce.
A new, concrete example is said to be an app called Better Fonts Free. Just recently the title lost all of its June ratings overnight, causing it to plummet from over 20,000 reviews to less than 4,200. While pulling and re-uploading an app can wipe out ratings, Better Fonts Free has remained intact the entire time.
TechCrunch's sources claim that Apple did intervene in this case, and in fact cracks down on a regular basis if it discovers evidence or that evidence is brought to its attention.
Apple has been accelerating efforts to "clean up" the App Store as prepares to overhaul features for iOS 8. It has for instance been purging music download apps, and shrinking the size of charts.
