Apple has reportedly been removing fake App Store reviews that have improved the chart ranking of certain apps, according to TechCrunch. These rating removals have been going on for an indeterminate amount of time. A recent tweet noted one app saw 20,000 ratings removed “overnight,” and the report claims it was due to Apple’s intervention. 20k ratings gone overnight? Without update ?
