Most people aren't willing to help expose what they know is wrong. It's possible to have schizophrenic delusions of grandeur and still function. Someone appearing to have integrity may still not be right. Lots of unverified rumors don't add up to truth. Things that sound too good to be true probably are.
Most people keep quiet about being ripped off.
The main stream media won't always investigate scams. We all crave hope and exciting news. People would rather cling to a faint glow of hope than admit losses. An experienced huckster will have answers to everything.
