I can see buyers wanting privacy of what they buy but a seller who hides the items they sell is to be met with suspicion.
With all due respect, I guess that I'm one of the few remaining people that attempts to retain some online privacy in this day and age.
Why is it perfectly fine for buyers to have privacy, but not sellers? Why is it anyone's business what any particular seller sold, and to who? What difference does it really make? A substantial, mostly positive feedback score isn't good enough to warrant a possible purchase from the seller?
Rather than assume that something horribly nefarious is going on with "private" listings, maybe consider that the seller simply would prefer to keep his/her transactions somewhat private - for whatever reason?
The last that I heard, all of eBay
's buyer protection policies still apply after the sale, whether everyone knows about the transaction, or only the buyer and seller know about it.
