The company's attorney (HERO) must get involve in the case too.
It is not only the companies and brokerages that get served by lawsuits but all people who were contributing to their short action too.
For example, Mike dotcom comes to mind for manipulation (look at his posts). He has been throwing post after post with one purpose which to push the price down.
I don't think he will sleep tonight since he knows he has been part of this conspiracy to manipulate HERO for benefit of himself and his friends.
