two apps of mine almost only get 5-star reviews. However, recently a competitor of mine started writing fake reviews in the review sections of these apps to lower the score of my apps and even uses these reviews to tell people that there were better apps out there, with features that match exactly the features of his apps.
I contacted Apple about this issue and they deleted one review, that was obviously fake and contained bad language. However, they said they could not do anything about the other fake reviews, because these reviews did not violate their guidelines about App Store reviews. It's obvious that these reviews are faked as well, they even contain sentences like "this app is completely useless, it would need feature A and feature B to be useful." Guess who promotes in his app descriptions, that his apps contain feature A and feature B?
So after writing many messages to the Apple support they promised me to investigate this issue. That was a week ago, and nothing happened. This competitor of mine that leaves me these fake reviews is still in the App Store and even more of these reviews appeared in the review sections of my apps.
What can I do next? This topic really saddens me and it's quite disappointing that Apple did not do anything so far to protect me from this unfair behaviour of a competitor...
