Ask HN: Why there's no crowdsourced phone number blocklist?

2 pointsby electricantalmost 3 years ago
Lately I&#x27;ve been receiving a lot of spam phone calls. Being an engineer I started thinking about how to solve the problem and avoid wasting time and&#x2F;or being scammed.<p>I thought there ought to exist a list of annoying phone numbers like those that have been created for malicious&#x2F;advertising domains but I could not find any.<p>Why is it so that nobody thought of it? Am I missing something important here?

I don&#x27;t think a blocklist is the solution. I think the solution is to block all incoming comms by default, and require people to make exceptions on a case-by-case basis. The dark forest is for everybody.

Too open to abuse and being gamed for nefarious purposes, both of which result in a blocklist that&#x27;s effectively useless.

Any list that has enough accuracy to be useful is valuable, and isn&#x27;t going to be available for free.<p>Perhaps you&#x27;ve heard of <a href="https:&#x2F;&#x2F;www.nomorobo.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.nomorobo.com&#x2F;</a> ?

Many or most robocall caller IDs are spoofed, so a block entry has a short timespan - a few hours to a few days. That’s why many people use apps. Check out AT&amp;T’s free CallProtect app or your mobile carrier’s equivalent.

Quite the contrary, such lists are a dime a dozen. Search the web for the phone number—not for a list—and you should get several hits from different websites.
