It is extremely difficult to avoid leaking information somewhere, as others have pointed out. Eventually there's a trail.

People often (or at least used to) share their current location on Twitter without having any idea they were doing it. Venmo payments default to public, again something that people often don't know.

And often it's not you who leaks the information but someone you know. Good luck controlling the social media presence of everyone in your family and circle of friends.

Okay, so again how is the site to blame if your family or friends leak your info. I agree that these sites should be defaulting most options to non public until people explicitly choose for something to be public - but beyond that, the only thing I can see working is heavily discouraging the bad behavior, and we likely need the legal system for that. All a social media company can do is ban someone for bad behavior, not fine them or throw them in jail.
