>>79951720She is misrepresenting her ownership of the work in a manner that induces other parties to violate Jingo's IP rights. If Jingo went after the makers of that 3rd party merch as well, and they could prove they really believed that Filian owned the IP and had granted them permission, the liability could pass on to her.
So she could be screwed because of a bunch of merch that OTHER people made and she never saw any money from in the first place.
