Ebay auctions referenced at AudiogoN?

Does this bother anybody else? It sure does bother me. Why aren't these people using AudiogoN's fantastic auctioning system instead of badgering us with Ebay auctions? I understand seeking more bidders where they roam, but I for one am tired of reading "Up for auction at Ebay...". Am I just being a righteous goon? I have a very thick hide, so stab away if you feel so inclined.
