The Free Lobster Scam was a scam in which the scammer shouts something along the lines of "Giving away free lobsters, show inventory so I know how much to give you". The scammer expects someone to show their inventory in a trade, and then they will give the lobsters accordingly. However, this will be in the same trade box, and the scammer will accept, causing the player, who may not be paying attention, to trade their items. This scam is not possible if the victim has fifteen or more items, because the scammer would not have room for them, having less than thirteen vacant spaces in his inventory.
