If you want to go beyond the default blocklists, I recommend starting with the green lists on https://firebog.net/ and adding the appropriate blue lists under Tracking & Telemetry.

If you add these additional lists, be sure to follow the links under Whitelisting Suggestions.

@voltronic

thanks for this...i've been a lil remiss in auditing my list subs...need to refresh

@opie
Same here. I have a few lists that are no longer maintained because they load 0 domains when I update, but it scrolls by too fast to read. I was just going to post in the /pihole subreddit to ask if there is a way to generate a log for this so I can identify and remove them.

@voltronic

yeah, I actually used to pay for a list and they went outta business...and 90% of my blocks come from the steven black list

@opie
If you want a good replacement for that, this is where must of mine come from:

https://oisd.nl/

@voltronic

I use oisd as well, it's just checked after sblack...gets very few hits...not zero...but <10%

@opie
A very cool feature was added to the latest Pi-hole update which solves my issue with dead lists. The web interface now has an automatic health check for your lists, and marks the dead ones! Easy peasy.
