We can all see that this is a scam and there are red flags all over the place. It's easy to look back at their situation and wonder how the fuck they were willing participants, but I think it's probably a little more insidious. COS asks for money, they balk and are made to feel as if they are bad people and they feel isolated. When people are already vulnerable and lost, they're much more susceptible to this brainwashing. It seems ludicrous to us but I think in general we're all pretty sane and stable. (insert snark here). For me, I can't know how I would react if I were in a similar mental state.
