Quoted from CrazyLevi:This scenario is so convoluted and stupid I'm not sure how you would make a rule prohibiting it.
Quoted from gdonovan:Don't advertise a pin that isn't in your possession would cover it unless on consignment.
I've also seen "listing for a friend" situations too, but that pretty much covers it.
Listing a game that isn't in your possession and that you don't have permission to list is not cool.
The "seller"'s marketplace privileges have been suspended for now.
Thanks for bringing the situation to our attention.
