Article doesn't say, but why would I not be surprised to find that the fine is less than the amount of money that they made via this practice.
I would love it if someone found away to apply the RICO act to some of this crap so that they would forfeit all the money they made via this practice on top of any fine, and open the door to treble damages in civil law suits to boot.
As for punishing the share holders, maybe they should start taking a little bit of a closer look at the character of the company they are investing in. I would have as much sympathy for them as I would for an investor in a fund that pays 12% a year no matter how the markets perform, then is surprised that it is a Ponzi scheme.
Yeah, I know, it will never happen, but one can dream.
