I read an interesting blogpost: Domain Whitelist Benchmark: Alexa vs Umbrella
The author reported that around 1400 domains on Malwarebytes' hpHosts EMD blacklist were in the top 1,000,000 domains Alexa and Umbrella lists. I was interested to know how high these domains ranked, and fortunately they had shared the results. But I was not able to download the list (406 error).
Thanks to the detailed explanations, I was able to reproduce the results. I have 1413 domains on the Umbrella list and 1361 domains on the Alexa list.
Here are high ranking domains on the Alexa list:

It is interesting to see that domains on a blacklist score really high on lists that happen to be used as whitelists too.
