Man, you've really misunderstood what I've said. I was just referring to the claim that the short positions don't close, they just get added to and rolled over. I think the claim originated from the Max Keiser times of 'Buy Silver, Crash JP Morgan". That the price of silver would need to make a massive correction before it can rise to new heights, as they would need to close off their short positions.
Of course shorts are legal. I don't know why you felt the need to state that to me.
