So, I don't watch these types of videos. And nor am I subscribed to this channel. Yet, I've got a few notifications from them. After clicking one of them, I noticed that the comment section also had the same thing happen with lots of them having been notified of this video. I'm confused. Is this like a paid thing or something? Cause that's incredibly annoying then. I don't want stuff I'm not interested in to appear.
