    I am using Prosper2020. Let's say I placed an ad on Facebook, but the link goes to my prosper tracking link. Not directly to the offer URL.

    The network should now see that all traffic are coming from my website. But they rejected all visits because it was from Facebook - which is true -. My question is how did they know what are the sources to my tracking link?
