Enforce the margin calls on shorts that are way out of money. If someone has a short at $20 and the stock is at $70, they shouldn't be able to short more before they cover their previous loosing shorting positions. Also prohibit share borrowing from cash accounts, my shares are my own and I don't want to lend them out to shorts... That's like shooting myself in the foot.
