Not really. Not having fraud would be a huge competitive advantage, so of course ad companies are investing huge resources into fraud prevention.

That said, the assumption is that advertisers are the victims here. However, in reality ad spending is driven by huge multinational, bureaucratic and dysfunctional companies. For many of these companies the goal is simply to spend the allocated budgets, and forget about sanity and KPI-driven processes. In that sense advertisers and fraudsters are willing accomplices.
