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 Groo.
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.
“Great seller, game was as described. Deal with confidence!”
