That is annoying, isn't it? I like feedback that gives me a little bit of information about the transaction and satisfaction with it. The same is true of "asset to eBay," which is very nice but doesn't really tell me anything about the transaction.
Probably one guy who blamed me for his shipping mistake.
He shipped the wrong product and said something like "Unconfirmed address = wrong product"
I replied "Confirmed PP addy, how is that the wrong thing in the box" something like that. I laugh about it now though
