bartermania.. Occam's Razor. What's more likely: A) The stock is down because of naked short selling or B) The stock is down because the company has no profits and continues a pattern of issuing new shares and dillution.
You just need to wake up to reality here. If the stock were making money, Turek could flush out shorts with a dividend. Unfortunantly for PLNI shareholders, PLNI hasn't shown the ability to produce a single dime in profit.
