I think the point is, the problem isn't a problem if it is priced into the product. It's cheap as hell to show ads on a cost per delivery model because the value is low, in part because of bots, in part because people don't click on ads much and in part because it's not clear how useful they are for building brand awareness. If there are more bots than previously suspected, sites will need to charge less to account for that. That's how the market functions, not a sign that it is not functioning.
