Not to mention the fact that it's hard to get short shares of a penny stock as a commercial investor, and once you have them, you face the same low-liquidity problem that everyone has in that market. Pennies are a market that are slow(few trades) and fast(massive price swings) at the same time. The people that play them seriously wage a war of information, and sit around waiting for every tick all day, posting on forums, trying to discern the actors and their intentions. And it's frighteningly easy to deceive oneself into following pumper's tips, like those 50 gave. It just has to be heard from someone you trust, at a vulnerable moment.
