The new guys don't normally go to jail, they are not risking their lives. They are looking for a pay check. They just say they didn't know and were lied to as well, even if it's not the truth. They could also be well aware of the scam and are scammers themselves looking for a piece of the action.
Seen it happen over and over with share selling scams.

I expose stock scams to gain knowledge about investigating the stock market players and for the entertainment it invariably generates. I've received NO compensation in any form for such, except for a few thank yous...
