I am using the Default servers from Adguard DNS which should block Ads, but I am still seeing Outbrain ads on every page I visit. See I'm not talking about trackers, I'm talking about ads.

I did an experiment to try to block Outbrain ads via domain.

1) Go to the link: https://www.lemonde.fr/international/article/2023/07/03/un-bureau-pour-enqueter-sur-l-agression-russe-en-ukraine-ouvre-a-la-haye_6180385_3210.html Using NextDNS, I only enabled the Adguard DNS blocklist, which showed exactly the same result as using Adguard DNS (obviously). You will see Outbrain Ads, like this: https://i.imgur.com/3Tt3LyX.jpeg

2) So in NextDNS I blacklisted only one domain (images.outbrainimg.com), keeping the AdGuard DNS filter blacklist enabled. The result was this: https://i.imgur.com/0DNDVfB.jpeg

3) So in NextDNS I blacklisted one more domain (in addition to images.outbrainimg.com, I added widgets.outbrain.com), keeping the AdGuard DNS filter blacklist enabled. The result was this: https://i.imgur.com/72qESYA.jpeg https://i.imgur.com/pJY02S3.jpeg

As can be seen, if Adguard DNS adds to the blacklist the domains widgets.outbrain.com and images.outbrainimg.com, then Outbrain ads will be finally blocked in desktop and mobile pages.

As I said, the Adguard DNS Default Servers list blocks not only trackers, but ads as well. Please block Outbrain ads in the AdGuard DNS filter.

At least on the official website (https://adguard-dns.io/en/public-dns.html) says that this block list should block ads too, not only trackers. Correct? If you block ads, then surely Outbrain's ads should be blocked too.

Redirects are blocked, so I guess it is not a problem to block this widget. But without blocking widgets.outbrain.com / widgets.outbrain.com/outbrain.js to avoid some anti-adblock decections.
