well in my particular example it's a juicebar she frequents when she's had a bad day. So, she probably lives or works in the neighborhood. And a detail I didn't share was that she was attractive (her icon on the map was her headshot). So someone could get it in their head to approach the person and know what she looks like, where she might be, and believe she needs cheering up
And it's NYC which has all sorts of people, many of which you may not want to be approached by.
If the juicebar gets tagged, then the people working there may start interacting with the friend in a way she may not appreciate.
Sending out life specifics, even if your not famous or have a stalker can be detrimental. And, it wasn't the friend's choice either. So, the original poster may loose a friend in exchange for likes on X.
The thing that never makes sense about this threat model is she lives or works in this neighborhood, which in NYC is many thousands of people. They see her, they can approach her, they can follow her back to her apartment if they chose. To get to said juice bar, she’s likely walked past a dozen mentally ill homeless people and maybe ridden the subway, where you’re confined to a metal tube underground with NYC’s most interesting for minutes at a time.
But none of that registers as a risk: instead it’s a hypothetical X user who is so struck by a headshot on a map that they travel across the city on the off chance she’s still at the juice bar? That’s like worrying about being struck by a meteorite, but paying no attention to the risk of getting hit by a car.
