Exploit for that will give you unlimited XP

I know about it

I can see if I can combat it at some point, but I would much rather put my time on creating new content for the game. If someone wants to cheat xp there is always a way, with some cracked .apk. Fortunately, even if a player decides to grind xp in this way, it does not at least affect other players in a negative way since there is no leaderboard or such with these parameters.
