How can I report someone anonymously for copyright infringement on various companies?

I saw this girl named *lilineko on DeviantART who is making fleece hats of several copyrighted characters (these characters include Yoda from "Star Wars", Garfield, Winnie The Pooh, Hello Kitty, aliens from Futurama and several amine shows as well) and she even making profit out of it! How do I report her to the various companies that own these characters for copyright infringement.
