A few years ago I bought a couple .us domains on Namecheap without realizing that Whois Privacy isn't supported and accidentally doxxed myself. My main phone number was basically unusable for a few months with constant spam calls. I quickly changed the Whois info to a burner number but the damage was already done.

Ended up setting up Google Voice to immediately go to voicemail for all non-contacts and used a generic "this phone number is not in service" message with that ascending tone. No idea if that actually had an effect but the number of spam calls plummeted after about a month of that and is basically back to normal now.

I'm still steering clear of .us after that experience...
