PC World reports a ratings scandal resulted in the removal of more than 1000 iPhone applications from Chinese software developer Molinker from the Apple App Store:
The discovery of the phony reviews was made by a frequent reader of iPhoneography, known only as SCW, who recognized a similar erratic and poorly-written tone to many 5-star reviews of Molinker apps. SCW wrote a (long) letter to Phil Schiller, senior vice president of Worldwide Product Marketing, revealing the major fraud. According to the e-mail, SCW "looked at 44 of the reviewers who posted reviews for this Molinker Inc app 'NightCam Pro' & EVERY Review except 2 of the 44+ are ALL FAKE 5 [star] reviews."
The phony reviews didn't stop there. SCW posits that Molinker employees obtained and redeemed promo codes in order to access the US App Store and publish an "endless slew of fake postings."
