It is amusing, additionally to see Reddit users being carried away with what they're doing, various comments about "defeating" Wall Street, etc.
Pump and Dump doesn't need you to supply bad news though, once you've pumped it, you sell and that's that. Suppose you could decide to just **** around with the price for fun, but would think you'd want cash out of it, especially as you burn a bridge once you've done it (or have a high chance to). Sort of odd that this even happened though, could have sworn naked shorts were illegal in the US.
