ebid did respond to this issue and another related issue months ago they cleared out thousands upon thousands of duplicate auctions a sizeable amount of these were listed by absent sellers the total number of listings at the time was around the 3 million mark they droped to about 1.4/ 1.5 so ebid do listen to members concerns.
i doubt very much ebid is going to mass whitch hunt apparant absent sellers, if you have a concern about a non active seller that you [ or any one else ] has tried to buy off, then report the auction/ seller, ebid then have a clear mandate to act,
