This was a quick project to make a list of commonly whitelisted domains derived from this pihole fourm post: https://discourse.pi-hole.net/t/commonly-whitelisted-domains/212)https://discourse.pi-hole.net/t/commonly-whitelisted-domains/212
The raw whitelist is here https://raw.githubusercontent.com/cedwards4038/pihole-whitelist/main/whitelist.txt
My Version for AdGuard is Here: https://github.com/cedwards4038/adguard-whitelist/tree/main
You should be able to copy this codeblock to add everything pihole whitelist at once
