Good idea, simple, yet effective, however cant people just lie about whether or not someone is scamming? This might make their trading lives alot harder for no reason, but i believe the majority of the public will use this service well and we'll actually be able to see who we can trust/not trust in trades.
Tip: One should always check item values before engaging in a trade; take higher precautions with high value trades - obvious.
Never entrust your items to another player, they cannot be reclaimed if that person chooses to keep the items. After all, you did accept to a 'trade' not a loan contract...
