Who said anything about passively earning money from illegal activity?<p>I&#x27;ll clarify - by &quot;we should hold networks responsible&quot; I mean &quot;we the publishers&quot; - that doesn&#x27;t absolve our responsibility to the consumer. The fact is, the overwhelming number of ads online are free from malware, to a large number of 9s-decimal places. Still, networks need to vet the ads they serve. That&#x27;s something they _can_ do that publishers cannot.
