I think that we should organize something, this is unacceptable to me that nothing has been criminally filed. He (BTC-ARBs), has the burden of proof to show that he was hacked.
The reason you haven't seen anything done is, he's been attempting to pay people back. A criminal action would result in incarceration, which wouldn't see anyone's money returned. So far, for about a year now he's been gradually making payments. Not a ton, mind you, but he's continued to pay people and hasn't attempted to vanish. So we have just let him continue trying to make it right.
I would like some immediate transparency. How many more BTC does he need to return (his list). How many BTC does he have. How many USD does he have. What transactions is he making on a daily basis. A website back up that is solely there for this purpose. I mean, the price has dropped significantly in BTC. Do a home equity line of credit, something to make it right.
There needs to be some motivation to be more transparent and I am not sure of another way at this point.
