Maybe not, but I'd want to know beforehand either way. And looking through accounts near me suggests that a fair number of users add enough detail to make me think that they don't realize that their info is so public (selfies/profile pictures being the most problematic example imo).

Depends on what linking credentials you may have registered with. If they have a data leak, those details will be linked to your address in that way.

Seems pretty unlikely even with a data leak, that someone would go through the effort, but it's worth acknowledging as a vector.

Yah, this is what I do, however I think this is what GP is talking about when they say savvy (or maybe I'm flattering myself). Plenty of folks with their full details on their profile.
