Fwiw, I've been maintaining a list of mobile ad and analytic domains for a few years now located here:

https://github.com/jawz101/MobileAdTrackers

I use a combination of Adaway, NetGuard, and pfSense pfblockerNG to catch ad domains specifically coming from app traffic. I also merged domains found in Adguard's mobile blocklist as well as from a list from the Exodus Privacy Project- an organization funded by France specifically to analyze mobile ad networks for their privacy and legal practices. I also run it through a utility to make sure the domains still exist.

Anyways, I thought I'd pass it along. I have a little write-up in the readme but there gist of it is:

- most blocklists out there are compiled by monitoring desktop and browser traffic so they don't necessarily see all of the domain lookups we see from mobile ad/analytic sdk's.

- approx. 41% of the Adaway host file is a bunch of dead domains so I don't use it.

- I just download crappy apps and run them a while why watching NetGuard logs an Adaway tcpdump. Picking out all of the crap, googling the domain names to see what the company does, test to see if blocking breaks anything, and then add it to the list. It's pretty easy to spot these sorts of domains.

- about half of the domains on my list are not caught by other lists I've reviewed.

And finally, the only other list I recommend is Steven Black's Unified Host file (also on GitHub) and maybe hphost ad and tracking domains. Steven Black's is the most useful because he merges a bunch of the well-maintained lists, scrubs dead domains, and, if I load his and mine 1st) in pfSense I see it and my list catch everything while all of the other blocklists don't show any hits. Hphosts catches a few stragglers.

Anyways, pfblockerNG for pfSense is great. One thing it does as it loads lists is analyze each list for duplicates. Steven Blacks list and hphost pretty much negate all of the other blocklists out there so that's why I stick to those 2 and mine.

Anyways, the last time the Adaway host file was touched was a pull request by me last year which was quickly reverted because of a goof on my part. I hope they reconsider my entries but I guess I'm covered so whatever. It would be nice to see them trickle into the other lists if they were ever to be merged, though. As of now, Adaway's own list hasn't had updates for over 2 years and half of it is dead anyways.

I'm just trying to curate a list of actual mobile ad activity. My browser's ad blocker blocks the browser ads.

BTW, if you want to test it out, try blokada with all of your favorite lists enabled, and then add this list . If you have notifications on in blokada you'll see the difference in how many lookups get blocked. If you like the blokada notification feature before you'll probably disable it afterwards.

I don't like speaking up but I just wanted to pass it along. The one thing I wish to get is more international ad and analytic networks because I probably don't install the same sorts of apps that likely only have regional appeal, so if you have additions submit a pull request. I may Google to see what kinda business they are just to be sure but I do want to block as much as possible with extreme prejudice :D.
