Open vs. obscured

that’s probably too hard to control, especially when places overlap.

i think this is the closest thing that has been contemplated that is similar to what you’re describing: https://forum.inaturalist.org/t/automate-geoprivacy-with-user-defined-geofences/700/9. (i’m personally opposed to this – at least without some very thorough testing – but my opinions on these sorts of things tend not to be popular.)
