Shorts "borrow" and then sell stock to establish a short position. When they close out their position they buy to replace the shares they "borrowed."
So it was more likely someone borrowing and dumping a large amount of shares to establish their short position. That's fine with me. I'll buy up shares at 0.26 all day long. It also didn't have the intended effect to the price, which continues stability at 0.32-0.33.
Anyway, a huge short position just plays into the hands of longs right now, since the price is likely to rise and cause the shorts to buy shares in order to cover their position and not lose more money, leading to a "short squeeze" that accelerates the price rise even faster.
