I think the SEC and DOJ already believe Matt Brown used iHub for illicit gains. However, I believe that part is peripheral as compared to the wash sales and matched orders from nominee accounts, and the money laundering. Ultimately, I don't think the SEC cares much what happens on message boards.
But, who knows. Maybe there will be some big Armageddon on iHub because of it. I just think the Octopumpers will get fined, jailed, and iHub will go forward without much change except for some new policies maybe.
