Back in the old OTC days with NO Reg SHO, big guys (M&Ms and insiders) would manipulate 4 or 5 OTC stocks a week for huge runs. That was pre 2010 or so. And took place by M&Ms front trading the OTC 2 tier trading system and using foreign exchanges (Germany)as a reason they went naked short. Insiders would plan their manipulation and drive runs out of no ware.
Now days if you see a darkside play (Rare maybe 1 or 2 a month) it's real quick because the M&Ms have only a few days to cover their naked short positions.
Here's a video I posted back then, explaining the wild west OTC game.
