Quoted from TigerLaw:

Said he sold his MB on Pinside in twenty minutes but then moments later recorded it as unsold in our archive. Perhaps he didn't want to pay the small fee to Pinside or perhaps the deal fell through and he got frusterated for whatever reason (maybe his other thread being locked bothered him) and hasn't come back to the site for awhile. Who knows, all matters (the MB sale, this thread, his other thread being locked, etc) seems to have happened at about the same time.
