When ending a MarketPlace listing successfully, Pinsiders can invite user feedback from the other party. Marketplace feedback cannot be removed, but can be responded to by AAAV8R.
New! It is now possible for any Pinsider to leave feedback, without an invite. There are some checks in place to avoid abuse and "fake" feedback.
“Sold two pins to this Pinsider. Very reliable and Easy to work with. On both occasions he's been extremely transparent and followed through with his commitments. I would feel very comfortable selling to or buying from him.”
