Pete in my old PiHole days I use wally's list(s) too but since NextDNS and OISD, that's not needed.
The OISD dev also remove all false positives and already use an big whitelist so even bad sources aren't a problem. See: https://oisd.nl/excludes.php
I use only his list with "No facebook" and never look back to any other. NextDNS default list is also disabled in my config as it sadly include bad sources like Steve black without that kind of whitelist like OISD.
