We all know about eBay and most of us have bought something through the service. You hope that the transaction goes well so you can get your hands on that rare collectible, Halloween costume or latest tech gadget at a steal of a price. If all goes well, you throw the seller a little feedback love.
However, what happens if the transaction was botch in more ways than one and you end up not getting your item, it doesn't come as promised, or you felt you were jacked by $100 in shipping charges? You'd do what many have done - leave negative feedback on the seller's profile.
Be careful though, you might get sued.
