Great game but crashes and crazy people

On YouTube people records and sos playing Pokémon GO in a graveyard. Some play it while Im they are on mountains and fall off a cliff. And some people dont go out and just play in their houses or wherever they go just not walking. Pokémon go crashes sometimes, but sometimes it doesnt crash. I gave it four stars because I like it but it crashes.
