Until last year, I was completely unaware of this problem. I made a stupid, stupid mistake - registered a .us TLD using “Google Domains” - within minutes of registration, the calls started. Some Indian voice offering website construction, ios app, android app, tech support, on & on…over 100 calls in a single week! Used call block but they kept coming. They switch numbers and send 1000s of text messages - neverending…
I actively avoid Google products, but Google Domains is an exception. They make limited upsell appeals, their pricing is straight forward, and if it's available, they include privacy protection with the annual cost.
And they are clear about the lack of privacy protection for .us domains. This text appears when checking out: "Privacy protection is not supported for .US domains."
