The site has been contacted by another develop who's had their app discovery tool blocked by Apple for violating regulation 2.25 which says "Apps that display Apps other than your own for purchase or promotion in a manner similar to or confusing with the App Store will be rejected."
Notably, the app was refused for "filtering, bookmarking, searching, or sharing recommendations" which isn't explicitly prohibited in the regulation.
The developer who wished to be anonymous said the app is primarily focused on sharing recommendations to your friends.
"I have not seen this rejection notice before and believe that it is a new one. We thought that basing our recommendations on sharing was suitable for Apple, as it had previously stated that if you bake in social or local into your app discovery, you would be fine. However, either we are not social enough, or Apple is going back on its position. Either way, it appears the scope of 2.25 continues to grow and I think they aim to be the only provider of recommendations for apps, along with being the distributor."
Controversy over Apple pulling applications that recommend apps was ignited with the removal of AppGratis from the App Store.
