CrowdSec

CrowdSec is a security automation engine, using both local IP behavior detection & our community-driven IP reputation database.

- Open Source
That's one of many reason why https://crowdsec.net/ was created. It collects (anonymized) threat intelligence from all users, vets it and distributes it as relevant blocklists. Once there's enough users it will be a very effective way to fight bad guys. And unlike your suggestion it DOES make a difference. Currently around 800k signals are collected daily and there's around 19k vetted malevolent ips distributed to users.
