Correct. While we do use Facebooks tracking for ads placed on Facebook, traffic from all other source is piped through a partner that does referral tracking and ensure that we aren't paying out commission to more than one referrer per sale. I easily imaging someone wanting to funnelling everything through one advertising/tracking partner for simplicity.

Facebook needs to ensure that their setup works in a way that the rest of the business expects. What Facebook seems to lack is the resources and dedication of Google to find the fraudulent ads.
