Any type of trading system is exposed to the possibility of scamming, that's honestly just a given. Unless you do an update like what was done on Runescape til they removed it, where they added a price range for each item and players were required to match that price range of the item they want, or else they couldn't trade at all. This meant no free items given out by players and no scamming prices. The thing is though, it's a very unpopular security restriction.
