I know for certain that there are Hermes Brand Protection employees in those Facebook groups and more than a few of the resellers have been blacklisted; though it’s usually not a big legal-letter thing, it’s more of the SA/SM blocking bag offers without any word to the client. Many of these clients don’t recognize what actually is happening as the current legitimate low inventory environment gives good cover to the “sorry, we have zero wishlist items right now!” story. As inventory and offers get more plentiful on Social Media, I predict hearing more and more complaints from confused clients wondering why their previously good relationship has “suddenly” turned sour.
