Why are people like this?

Won't get scammed if you never expose yourself to them.
With Belle, yes, it was her wellness empire which you could choose to not expose yourself to.

But what do you do when Amanda and Elisabeth are your friends? Family? Coworkers? You're simply responding to someone whom you know and perhaps love that is going through an illness who knows you will not ask any questions.

And it's not just the money. It's the false empathy others who WERE ill were betrayed with as the scammers express that they are "going through what you're going through".
