Google has updated its developer policies to ban on device cryptocurrency mining apps from the Play Store. Still permitted, however, are apps that allow users to remotely manage their cryptocurrency mining activities, or apps the enable cloud-based cryptocurrency mining. Apple has also instituted similar policies as the apps can stress hardware to the point that they lead to component failures.
The new policies also ban a number of different app classes. These include repetitive apps that clone or deliver virtually identical user experiences as other apps on the store, particularly if they don't add unique features. Apps that have been generated by automated tools, wizard services and based on templates have also been kiboshed.
The Mountain View company has also barred apps that appeal to children, but contain adult content. Also banned are apps containing adult content of any description. This includes apps promoting escort services or "be interpreted as providing sexual acts in exchange for compensation. Apps promoting hate speech, or are discriminatory, promote violence, terrorist content, or facilitate the sales of firearms are also on Google's hit list.
