Re: Jpop actions criminal? Sorry, I just don't see it. Basically, he would have knowingly had to be attempting to commit fraud. As much as a few on here want this to be true, the legal test for this is pretty steep. Proving this would be nearly impossible. Is he an idiot? Yes. Is that a crime? No. If it was, half this country would be in jail.
Re: Jpop actions and civil liability (ie: lawsuits)? I did some looking recently and this one is quite interesting. Given that John is a horrible businessman (I don't see anyone able to debunk this one), I'm having trouble find any true legal business documentation. In order to protect his personal assets from civil liability, he would have to either be a corporation, LLC, etc. He calls his company Zidware Inc but I see there is already an unrelated Zidware Inc in IL. So, did he REALLY incorporate? If so, where? I couldn't find any reference. Maybe you guys who signed the NDAs and have other legal documentation may have more details there. But, if he doesn't have his ducks in a row from a business management side (this is unrelated to keeping good books), he can be held personally liable for the debt that Zidware incurred.
If he does turn out to be incorporated, then the only civil liability I can see that he might be responsible for would be if someone can prove he was negligent in the operation of the company. This will be much harder to prove and even harder to actually collect on (if proven).
I wish all you guys that have skin in this game the best of luck!
