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 PinbBall233.
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.
