This is why the BCP scam is so good.

Man I wish I wan't practicing the "Do No Evil" lifestyle. I would love to pull a BCP type of scam myself.

I would do some good (or at least make people think I'm doing some good). I would then scam (from a lot of people) little amounts. I would try not to scam the people who think I'm doing good.

Once people realize that they were scammed, they would not say much (if anything) because of the small amounts.

What if the scammed person says something?

Who knows, maybe someone will call them a fool and they will shut up.

Maybe someone will let them know that (after all) it was their fault for allowing themselves to be scammed. They should have known better.
