Apple’s “walled garden” approach to the App Store improves quality control — but it doesn’t filter out all of the spammy, scammy content. According to a report by the Washington Post, scam apps represent close to 2% of the App Store’s top-grossing apps.
While that might not sound like all that much, it’s a sizable amount when you consider that the App Store hosts approximately 1.8 million apps. These scam apps reportedly have cost users in the vicinity of $48 million.
