Etsy has changed things so that now only the copyright holder can file a notice / report for take down. It needs to be either an 'authorized representative" of Hermes or in this particular design's case - Jonathan Burton. When I noticed another designer's designs being used illegally, I was able to locate a contact for her and wrote to her to alert her with links on where to go to file the claim. It looked to be successful, though there is a bit of whack a mole involved. Here is the link to report in case you'd like to share it with the artist or their representative:

.. Edited to add: I am not a representative of Etsy, or employed by them.
