That’s not how DDG’s app tracking protection works. It doesn’t trigger on websites. It’s not the links. It’s the ad service in the app. That’s why when you pay, the attempts stop. The dev himself said that the ad library doesn’t load when you’ve paid to remove ads (beyond doing an initial check to see if you’ve paid). Since paying stops the trackers in Sync’s ad library from loading, it no longer makes attempts and you won’t see it on this screen in DDG. If it really was the website, you’d still see it AND other Lemmy apps would show up here too, but they don’t.
