How often should I run a privacy audit on my social media accounts?

[Grace_P]

After a friend had an old, embarrassing post resurface, I decided to do a full social media privacy settings audit on my own accounts. I was shocked by how much I'd forgotten was public, especially on platforms I don't use much anymore. But even after tightening everything, I have this uneasy feeling that it's a losing battle—the settings menus keep changing. How often do you actually revisit and check these things?
