Why would anyone put in a "stink bid" of 3.28? How about "Because this stock has been at that price many times before, so what the heck, why not try to pick up some cheap shares that price?" And no buy limit order forces anybody to sell at that price.
As for the price action when the market is closed, I don't attribute much significance to it. By definition the liquidity and price disclosure is limited during that time. So all kinds of crazy prices can occur then, they don't mean much.
