Where do obscure users of a paid android application in Google Analytics come from?

Question

Android

I suddenly saw on the real-time radar of Google Play a relatively large number of users of a paid application from all over the world. It looks like users who use a hacked version and installed it not through Google Play. From what source could they come?

Answer 1

Piracy. Revenge :)
And if they broke it, the food is gone .... Your software will be in all file dumps.
