Pro-tip: anything you put on any service can and probably will at some point scroll past the eyes of a random sysadmin who's debugging why the database keeps crashing under load.

Most people are worried about "disclosure" - which is something Uber violated for a PR stunt at a party recently - i.e. we're usually okay wandering past the window naked, because we assume it's extraordinarily unlikely that someone will be pointing a camera at it right then, or that it wouldn't be more embarrassing for them to try and yell "hey that person is naked in the window I saw them!"

Conversely, we wouldn't be happy if someone did take photos, then uploaded them to the web, and showed them to all our friends etc.

In a practical sense, this is how people act. It's how you have to act - it would be practically neurotic to act any other way.
