In what appears to be a continuing effort by Apple to restrict ranking and rating manipulation on its App Store, the company is no longer allowing users to rate an app if it was downloaded using a developer promo code, according to reports.
An alleged letter from Apple customer support was posted by a Touch Arcade forums user
), with the unnamed rep saying "It is no longer possible to rate or review an app if it was downloaded using a developer's promotional code."
A popular strategy to help increase an app's rating has traditionally been to give an app away for free using a complimentary code, the assumption being that users would rate a complimentary app higher than they would have had they paid for it. It appears that Apple is cracking down on such manipulation.
As Gamasutra recently reported
, Apple has changed its ranking algorithm to make Top 25 manipulation more difficult.
This additional ratings restriction -- which appears to have been activated at around the same time -- is believed to be a part of a larger crackdown that Apple has yet to officially acknowledge.
