In legal terms, it’s interpretable as “don’t fault us for user-generated content”. While that may technically be correct, to host their UGC upload directory on an indexable share is — voluntary or involuntary — either cloud incompetence or cloud negligence. The work samples between a buyer and a seller should never have been made default-public through any process controlled by Fiverr, but certainly I’ll concede it’s both simpler and cheaper to do it through no-auth links and then externalize liability onto their customers.
