Finally heard from DomainMoon after a long delay. He claims his friend listed the names for sale, which names he did not want to sell, including the one I marked sold! There was a bunch of other names on the original post, all of which he edited and removed.
Assuming that is true, do not think a professional venue for domain business people should allow a member giving posting access from their account to someone else, and then also use that as a way to cancel a sale as has been done.
Very disturbed by this. Not because I valued the name so highly but mostly on the principles involved and the waste of time what with research on the name and on the seller (who somehow has managed to get good trader rating feedbacks) and my posts and pm's about this BS. What if is it was a $3,000 name instead of $30, the same thing could happen.
