I can certainly understand that when the situation is like, "I'm selling this over on Craigslist" or "I'm got this on eBay". That is the same as having a sales listing.
But if it is a situation of someone pointing out something that is obviously not theirs, that is intended to help others, and maybe point out something that may be in another's area that they are unaware of but would love to have, it is hard to understand.
Perhaps in situations like that, it could be allowed to ride for a week before moving to a location that folks don't visit daily unless they are here shopping.
It looks like we may have been able to help one of our own in this case.
