Hi all,
As mentioned by @ScamBot45 above, the best way to take action in cases like this is to submit a (DMCA) takedown request here:

We cannot reasonably check every single product for infringement, nor know with certainty who does or does not have the rights to distribute content. This removal request flow is a known, legal process for any website hosting user-generated content.
