It depends on the exact kind of ad, kind of tracking it uses, and kind of blocking method you’re using.
Are you ever 100% untracked?
No.
But this is a data game, the less you give up, the less they have, the less accurate it is, the more stale it is, the less specific things about you can be gleaned from it.
ublock origin + canvas blocker + privacy badger + forcing DOH by default?
Thats a lot better than doing nothing.
Much of the existing stuff doesn’t even load, meaning it can’t even attempt to assign to you a unique advertiserID, it doesn’t even get to the stage of trying to send you a specific ad, because you have no engagement with the system.
