If they own many shares, why should they take down the company? They paid a pumper to bring the price up, and then they could sell their shares. If this deal is going to go through, why they don't wait to sell at higher price? All they do is selling, not bringing the price down to buy.
From what I was told and it could be wrong. The people who hired shakerz were holding restricted shares that became available for free trading and there was a window to sell before they became restricted again.
