I use the following lists:

- StevenBlack hosts - WindowsSpyBlocker - WindowsSpyBlocker - ipv6 - Easyprivacy - Easylist - adaway - firstparty-trackers - d3host - w3kbl - Facebook - non regex - Peter Lowe Hosts

I also ensure that I have ublock origin on everything I can put it on. I’m sure the default lists are fine for pihole (I just like tinkering with things), but I recommend firebog.net for finding more lists if you so desire
