Wait, what makes it different? There's the old adage that half of your advertising money is wasted, you just have no way of knowing which half. Why would you willingly spend it on putting your ads next to content you don't want to associate with your brand? It seems exceedingly likely that this is the half that isn't productive.

(This is also what I don't get about the Twitter fake-account-number business and the YouTube videos-targeting-children business - if I were an advertiser, I would have no interest in spending money advertising to bots or to young children. I would prefer to pay for ads in front of 4 million users I want to reach than in front of 5 million users, 1 million of whom I don't want to reach. Why are advertisers not pushing back hard on inflation of account metrics?)
