In the legal version you need to find someone to lend you the shares which costs money. The more you borrow the more expensive it gets. So the transaction volume is quite limited. If you're shorting naked none of this applies so you can sell as much as you want (until the trade settles and you need to cover - or you just don't and laugh at the buyers some more).

This is what I don't get about naked shorting. Why are you allowed to sell something, but not prove beforehand that you have it to sell. And maybe have to put it into escrow too
