Because if you check TD banners, the merchant can update when they feel like it so this kind of rubbish gets in (Banners are pulled from merchants site in most cases).
Really it's about time we stop promoting any merchant that shows web address in banners (phone number I can't get over, that’s unreal). We are NOT FREE BRANDING, they want branding they can pay CPM, otherwise they should have a call to action like click here and not web URLs and the like.
