Minnesota-based freelance journalist Tony Webster is somebody you should follow on Twitter. He's been mining public records and other info to provide additional insight into what's going on in Minneapolis (my home town) right now.
You should check out his website, too. One thing that really caught my eye was this: Using domain registrations, security certificates, and Shodan to break news. He calls it, "A quick guide for journalists: how to spot new domain registrations, recently-issued SSL certificates, and new servers to report on political, business, and government initiatives." It's good stuff! It might need an update, as WHOIS output in a GDPR-compliant world can be limited compared to what it once was (thanks, ICANN), but there's still some very good stuff here.
