Etsy accepts fake DMCA counter notices

The problem is:

1. Someone is selling my art illegally on Etsy.
2. So I file a DMCA takedown notice.
3. Then Etsy removes the listings that I reported.
4. But sometimes the infringers file fake counter notices, claiming that they have the rights to sell my designs.
5. Etsy accepts those fake notices and restores the illegal listings.

I don’t yet know how to deal with this — I will need to consult my attorneys. Etsy is clearly accepting fake counter even though the notices are clearly not valid — for example, they don’t contain an address.

I don’t have a solution for this issue yet. I am simply writing it here to rise awareness. I know other must be facing the same problem.
