So this Randonaut thing is basically just Pokemon GO with slightly less danger and significantly fewer pokemon?
i gave it a quick go for curiosity's sake without actually going to the location. You don't really input anything besides choosing what type of random generated point type you want (aka a 'hot zone' or a 'cold zone' of random generated points), and it shows you a live GPS map like any other google map of your current location and destination. As far as your intent, it just tells you to think about something, not input any text of 'I want to search for _________' . So less chances of fuckery at least.
Pokemon Go had tons of people going to potentially dangerous situations to catch pokemon such as hanging around private property at weird times to get pokemon or even trespassing to get pokemon. It also didn't stop until you found the one point, it would keep showing you nearby pokemon.
This app on the other hand just gives you a point on a gps map and someone's confirmation bias kicks in to justify what they were thinking of. But without putting limiters where the random generated point can go, such as private property/land, I would hope people arent dumb enough to trespass anywhere not public.
