You don’t need to know the “contact name” of a spam caller, algorithms when reporting spam should work just on the number and so when it calls you, it should just show a Probably Spam flag, nothing about the identity unless of course the caller has given their consent to provide that info.

I get zero spam calls and on most days no calls. Should we give up on privacy because US has bad legislation regarding spam calling.

The spam calls are all using fake caller ID. So tagging them as spam only hurts the real owner of that number.
