Adding Cisco Umbrella "The popularity list contains our most queried domains. It includes TLDs, root domains, and subdomains."

I've PRed such a warninglist proposal. It's not exactly Top1000, as we've removed a few dozen TLD (.com, .org. .info, etc.)
Cisco umbrella is great as it's the traffic you're likely to see on the network, rather than just websites like you get with Alexa.
There are a few malicious domains in there though, these popped up on a quick check earlier:
