I believe it is all counterfeit at the end of the day so I do not think anything can stop them other than laws being enforced to locate every single share to borrow before they can short. How they could come into my account to take my money and make money behind my back while betting against me at the same time? Just mind blowing stuff!!
Whenever someone sets a sell price too high, the Crook MM's can still use them knowing the price is high enough that it'll prbably take a while before it gets up there. The price can be set low and moved up as price increases.
