30 days ago, I began performing an analysis of eBay seller *stoneark* (AKA stonark, AKA Corner Collectibles, AKA Cornner Collectibles) and bid participation patterns on his listings of “guaranteed authentic” wardrobe attributed to various classic Hollywood stars. As a result, I identified 8 accounts that share not only some remarkable coincidences, but nearly each one has transacted with all of the rest, in addition to buying from *stoneark*.
