It's actually very difficult to short a penny stock, requires high margin requirements, easier to do it offshore and, pretty much impossible in the US. Perhaps others here know exactly how to do it here, I don't.
I doubt that there is any shorting happening here, I just wish, that those attempting to actively get others to se by their own admission, would, actually do it and go short. Because, it would be a risky crazy thing to do and they'd likely get burned very badly :)
