Look at the page you are linking to though; it starts off with twentieth century propaganda posters — and just read that first paragraph! Their response will be that they are not a target for such scams. They'll say they don't have any enemies. That they only share their holiday pictures after they get back (so criminals won't know that they are away, they're not stupid). OpSec? They'll kindly let you know that it doesn't apply to them. And besides, admitting that leaving your private data all over the place means you'll be tracked, manipulated, monetized, and cloistered from anything outside of your comfortable bubble, would also mean accepting that the vast majority of society got it wrong. Try overcoming that cognitive barrier.
