NOBO lists have nothing to do with shorting. None of us would show up on that list, because you aren't a beneficial owner if your stock is with a brokerage.
My assumption is that the list is to find out about any shareholders that are NOT with brokerages and that are from the old management. For instance, if a company loaned the old company money, and converted it to shares, that could be discovered, because those shares would not be in a brokerage.
They are probably trying to find any 'missing' shares from old management.
How anyone could connect a list of names to naked shorting is beyond me.
