You don't understand how anything works, do you?
Once again, all that need be done to close any real short position held in this stock is to provide evidence to the broker that the stock is dead. FINRA's action to delete the ticker and suspend the CUSIP for bankruptcy liquidation is ample evidence that the stock is dead and never coming back. But let's play your little game and say they wanted more. The judges' final orders showing that the company was, indeed, liquidated and shut down could be offered, and then the fact that the issuer of the stock no longer exists, it has had its corporate charter revoked by the state that it was registered with.
All that eloquent BS you've written is just that, BS. If you really believe that a broker would leave a short position open for 5-6 years and would not take that first piece of evidence to close it, get some help to manage your investments, because you're not good at it.
I swear I’ll never use the phrase “you can’t make this stuff up” ever again after being on the OTC. Apparently you can.
