The post seemed pretty civil to me, just straight to the point. Everyone else is trying to solve the problem by banging a hammer into the nail more - maybe THIS way will help you show her it's a scam.

In my opinion, it's worth considering that she is aware(at least on some level) that this is a scam, and she just doesn't care, because she's too traumatized, because she longs for companionship, or whatever else reason. It's impossible to know without having a deep insight into michael_h's life, but it's worth considering.
