Is it worth registering my number with the federal government (which presumably already has access to my information) to avoid spam calls? Does it work? Is there a downside?
And also, why does this sub require a URL to post a question? Like, what if my question was so truly stupid that there was no related website?



In France, the Do Not Call registry will tell every company on the planet that your phone number is valid. Which means “more spam.” Hilarious, and I expect it’s the same in the USA.
