You are so brave. I get like 8 spammers calling me daily about loans like I owe them money, and that's without blasting my phone number out to the internet.
If you're not using it yet, then I recommend enabling the call screening feature on your phone, it has basically reduced my number of spam calls down to zero. It's available on iPhones and pixels and Samsung phones(and probably others?)
I started receiving spam calls lately again but I was just denying the calls. It was with a predictable frequency few times a week.
weeks ago I decided to use screening call, and maybe it was a coincidence, after the first usage I've not no more calls from them
