I definitely see your point, and I can't say that I disagree with the premise... but isn't that kind of the point? I mean for bad feedback to reduce a vendor's rating proportionately based on the amount of money of the listing being rated and how recent the transaction was?Perhaps you're being slightly too sympathetic toward a vendor not as upfront as yourself? I do think there should be a utility to scan the blacklisted buyers and compare the names and addresses against a new order, so that you guys can at least have some kind of protection without checking the list manually all day long... but the guy asked you to FE for an item he didn't even have in his possession yet. Personally I think a 5/5 is a little bit much, unless you were aware of it prior to ordering...
