Yeah thats true.. but as far as I can tell that advanced fraud is at an acceptable level. That level might be 15% of traffic/conversions.. but its not severely hurting campaigns. This is a weird answer, but all the fraud/viewability/etc is priced in to some degree. So an advertiser who wants less fraud can just spend more to get high quality impressions. The long tail is super important and you can't exclude it. How you can see those individual sites (by proxy) is through something like a supplier vendor, fold location, geo, etc.. so you can't see the site, but other factors you can bid will point to and show that fraud. I think my point is that a skilled campaign manager can get rid of fraud, but the average marketing manager can't. That is a problem for most businesses, but also why agencies specialize in things like rtb.
