DMCA is a copyright law. It requires a takedown for alleged copyright violation. That doesn't apply here. The stores don't have copyright over their domain names on a list.
Yes. So to get something taken down, all you have to do is allege copyright violation. If you're not concerned about perjury in the US courts, the claim doesn't have to have merit.
Service providers have a choice:
a) follow the DMCA takedown process and be shielded from all liability, whether or not the claim has actual merit
b) evaluate each takedown notice to decide if the material falls within the scope of copyright, ignore takedowns where in the service provider's opinion the material is outside the scope of copyright, and should it go to court, be forced to defend that position on its merits instead of having an automatic liability shield
What sensible service provider is going to choose option b?
