For the past couple of months I have been bidding actively against one of Yahoo's biggest advertisers (they are a shopping comparison site) for finance related terms. The problem I am having is that they have another domain they are also using to take up another spot. The second domain is obviously owned by the first as the corporate logo is at the bottom of the landing page. After complaining to Yahoo three times they still continue to let this practice go on. My Yahoo reps have even agreed with me over the phone that this is a violation when I show it to them. Anyone else had this problem? I'm getting ready to start stuffing the results myself!
