How do you know they do --- have you done a survey?

Some people value steady profits much more than a one time scam.

Why do some people become criminals instead of getting a nice steady job? Maybe because it is more profitable and requires minimal effort. And lots of scams aren't "one time".

Because where there is demand there is supply.
