All applications on BlackBerry World can be reviewed by any BlackBerry® smartphone user who downloads or purchases the application (trials are included). All reviews are automatically scanned for malicious or vulgar language, and are approved if none is found.
A vendor may log in to the vendor portal for BlackBerry World and flag reviews that they feel should be removed. Once a review is flagged, the BlackBerry World team is notified and the review is examined for vulgar and malicious language that may have bypassed the filter. Reviews with no constructive information regarding the application are denied1. Not all reviews are denied if they are flagged; the BlackBerry World team decides when to deny a review.
Application ranking is based on an average of all reviews submitted for a specific application. BlackBerry smartphone users can only read reviews posted by BlackBerry smartphone users who have downloaded the same bundle (for example, BlackBerry® Storm™ 9500 smartphone users can only read reviews posted for BlackBerry Storm smartphone only bundles).
1 Denied reviews only remove the text portion of the review. The ratings attached to that review are still a factor in the overall application ranking.
