@sheogorath Generally, the uBO community's approach is to write entries that remove such website notices, so that visitors won't even know that the website has such statements in the first place.
If you're already using uBO but still see such notices on a few sites, turn on the 'AdGuard Base' list in uBO's settings. If that doesn't remove all of them either, report the remaining ones to uAssets on GitHub.
@dandelionsprout See, that's where I disagree with the uBO community approach. When I visit a website and they have ads, totally fine. I block them, all good. When they block my adblocker, there is a cat and mouse gaming starting. I block their blocker, then they block my blocker blocker, then then I block their blocker blocker blocker, etc.
The straight forward solution is: I take them out of the game. Out of the web. They simply no longer exist. Problem solved permanently.
