500px photography app returns to App Store following controversial ‘pornography’ removal

One week after it was unceremoniously booted from Apple’s iOS App Store, 500px has returned. The app is once again available for both iPhone and iPad after it was pulled down last Monday. In a statement at the time, Apple explained that the 500px takedown came as a direct result of the app “featuring pornographic images and material, a clear violation of our guidelines.”
