Comments?: NOPE.
Legitimate questions about the item being offered?: YEP.
I think if you make a prospective buyer PM the seller for a question about the item that may be glaring that the seller overlooked he now has to answer a multitude of PM's about the item. If I have a question and it's already been answered in the thread by the seller I don't have to waste a PM and wait for an answer.
Tough to police? Hell yes.
