This is true. The problem is stupid buyers. Many people here would be shocked at the lack of sophistication (or 'sophisticated buying theater') some marketers use to deploy 8 figure annual marketing budgets. It's getting better slowly and as it does we'll see less of this kind of crap.

To their credit, many of the DSPs (at least AppNexus) are trying to clean up their own systems as well and automatically block this type of traffic from being purchased. The trend in ad-tech right now around viewability and viewable eCPM metrics is also a step in the right direction.
