I have been doing some research and found that on the guys who run no reserve auctions they seem to have a lot of the same people bidding on their pipes. One guy I saw bid on 11 different pipes from one guy. Another guy has been jacking bids by bidding as many as 35 times on one pipe. I have seen him bid on 5 different pipes from one guy and followed him to other sellers and he does the same thing on their auctions. I am collecting names and once I get enough I am going to have Ebay institute an investigation. So be careful guys, check the bidding history on a pipe you may be interested in and if you see this kind of behavior, report it.
