Yes, however since there's never been any proof of counterfeit shares on GRNO, I think the pump and dump is a far more likely explanation for both the move up and down.
And of course there's still the questions of what happened to the 24.5 million shares given the CEO of GRNO in July 2009 that he no longer owned by YE 2009 and how many does he currently own of the 60 million originally given him. Selling those shares would have added a huge supply to the float, though of course, they are not technically "dilution".
