I've started encountering the ad-blocker blocker myself over the past few days, but fortunately it proves to be terrible at its job in my experience, as a small X allows it to be dismissed after 3 or 5 seconds, which is outright better than waiting for the 5 seconds plus load time of a skippable ad, or the many more seconds of an unskippable ad or two. This might be useful for me if they ever decide to remove the ability to dismiss the ad-blocker blocker, though.

I played the first two Splatoon games quite a lot, but elected to skip the third, since I felt, and still feel, it’sn’t changed enough from 2 to justify itself as a same-system sequel. In spite of that, I was fairly active on the r/splatoon community on Reddit, but’ven’t’d any Splatoon interactions on the Fediverse yet. That’s probably at least partially down to me not contributing as much here as I did on Reddit, though; much of what I did on Reddit was answering questions about videogames I cared about, and most of the communities for games I care about here either don’t exist to my knowledge, or are small and subsequently have relatively little content to interact with at all, much less people posing questions about the game.
It's an ad blocker blocker they've been implementing as of late. I don't think you'll be banned if you continue disregarding it, but they do eventually entirely block the video player unless you disable the ad blocker. However, in my experience, uBlock can block that message to resume normal watching. (Double Edit: This method did stop working on the 15/10/23, but started working again a day later. I guess it's a question of if the filters have been updated to counter YouTube's updates, though I did notice that viewing in a private tab worked when regular browsing didn't.) Go to the extension's settings/dashboard (on Firefox, do this by clicking on its icon in the top right, then the settings icon in the subsequent pop-up), then the Filter Lists, click "Purge all caches", then "Update now". Open an entirely new YouTube tab (or hard reload your current one by pressing Control + Shift + R), and the message should stop appearing, at least for the time being.
