&gt; Facebook has a massive incentive to stop fake accounts<p>As an advertiser, I am pretty certain this is not the quite case in (current) reality.  A large part of FB&#x27;s proposition for more money from us includes:<p>A) Pay more for increased reach and engagement.<p>B) Our traffic isn&#x27;t decreasing (despite outside reports&#x2F;indications to the contrary) and you would be missing a massive and engaged audience if you didn&#x27;t spend with FB.<p>This combined with the fact that a _lot_ of ad-spend isn&#x27;t directly attributable to conversions (often by design), means that more &quot;activity&quot; whether its fake or not, drives up ad-revenue for FB.<p>You see the same issue occur with other publishers by the way.  -It is not uncommon for a publisher (or other related party) to purchase a swarm of fake bot traffic to boost impression and engagement numbers of an ad buy they&#x27;ve sold.  -Advertisers un-aware of how much of the traffic to their ads are bots vs legitimate humans (read: &quot;publishers stealing money from advertisers&quot;) is a major problem for advertisers, but the bigger the publisher, the harder it is to &#x27;not&#x27; be on their platform too. (and FB is _very_ big)
