no, it is because leaving f/b is a voluntary thing and some people would rather say nothing than something not-so-nice or else they are too busy to bother, or they dont see the point of ebay f/b, especially as a seller can only leave a buyer pos.fb and every buyer-only ID only has positives, so what's the point is the question many sellers ask.
does it really matter?
as a seller I do always leave f/b but whether or not my buyers leave it is up to them
