I concatenated every BlockList I could find then transforming the lists to start with 0.0.0.0 and 127.0.0.1 depending on source.
It took Over 50 Man hours to create and modify this list with the bulk of the lists provided by @WaLLy3K
Includes InBrowser Mining and sites that run them. You may have to WhiteList a few sites.
I am running on 2 Pi-Holes currently for the main use of my YaCy Search Servers.
I am running 1 on a Raspbian 3B it consumes around 2 Watts on the power bill it cheaper than a cloud and more convenient.
The Actual number on a clean Pi-Hole is 978022 Domains on BlockList I may update with a few more like the pic after testing.
