A friend of mine was renting a room in the house of a lady who lived down the street from me. She had been suckered into a Nigerian 419 scam, was convinced that the people she was communicating with were "Good Christians", and sent them about $30,000. When she took out a loan against her home, her daughters attempted to intervene with the courts to declare her incapable of managing her assets. She ended up losing the house and all her money, and my friend lost his room.
She was a nice old lady whose mind was starting to go, and unfortunately was taken advantage of by some cold bastards. Don't mock too hard, it could be someone you love or even you one day.
