Sorry for the throwaway, I work in ad tech. Other posters are saying they see hardly any fraud on Facebook. My employer is a more traditional ad tech company (think exchange and direct buys) and we estimate 60-70% of our exchange inventory is fraudulent, and at least 15% of our impressions are delivered against fraudulent sites (of course we don&#x27;t tell the customers). In reality the numbers are probably higher. The problem is that literally everyone except the end customer is making money off this. As soon as anyone talks about the need to do something about it the whole &quot;let&#x27;s not rock the boat&quot;, &quot;what about our revenue targets&quot;, &quot;well you can&#x27;t tell Sales that&quot; crowd comes out.<p>I personally think there&#x27;s a reckoning coming soon to traditional ad tech. There is so much fraud, such ludicrous and impossible revenue and impression targets, so much pushback against shitty and annoying advertising, and so little incentive to be honest with the customer. It can&#x27;t last like this.
