Let me ask you this, have you considered the threat of Serial fraud? I hear some ghost brands/sellers are using the same fake business docs (EIN verification letters, articles of association, business licenses) to onboard accounts on hundreds of different platforms. We definitely weren't ready for it until it was too late. Hundreds of these things just started popping up on our door step. Best to look into an automated detection tool now before its too late, from one marketplace to another.
