Actually, you can think of it as a single pumper pumping a stock on a board as someone flicking you with their finger.
A couple pumpers getting together to try and move a stock as a bunch of bullies pushing you around.
Pumpers organizing to spam a stock as a gang of punks who'll beat you up.
Pumpers that use the boards to pick a stock in advance, frontload it or not, then dump it, as enforcers who'll break your legs.
Eventually, they have to be stopped before they become like the Mafia who'll rub you out! ( :
