Altogether too often these days, small 'rings' of userIDs seem to pop up with a low number of positive feedbacks each. In the old system, you could see the userID in full. Looking carefully, the 3 or 4 userIDs seem to work together and buy-sell from each other some music, or components and bolster each others positive feedback. At times and in one specific case I have experienced, it is only 1 or 2 people, all working from the same IP address(es) to put the setup in place. Audiogon will not legaclly pursue a fraudulent seller in my experience, or lend a user help to do so either but they will ban a user or an ad in relatively short order. The problem is the users come back with different userIDs, some even tied to the same or similar information and location a short while or up to a year later and start the ring all over again, sometimes using the exact same pictures and items descriptions they stole from somewhere else a year before to defraud other users.....unfortunately this is altogether too real on this forum and people have gotten burned.
