Officers of a company are never personally liable for business losses. That is not how corporate law works. Just because this is bitcoin does not suddenly mean I am personally liable.
IANAL but don't you have to be incorporated in order to get this kind of protection? Are all these usagi businesses registered and incorporated? I apologize if they are but every post and website relating to everything was deleted by usagi and I have no way to find out.
On that note why isn't usagi getting a scammer tag for personally deleting every bit of information about his businesses? I'm not even a shareholder and I'm finding it inconvenient. I can only imagine how much his shareholders have been screwed over by his action.
