Sometimes I do get YouTube telling me that I need to disable my adblocker to access a video, so they do try to block that stuff (though I suspect that the infrequency with which this happens combined with the fact that not everyone does experience it when some people do report this happening suggests that they’re just testing methods of detection and blocking)

Usually when it happens, I just go into my Ublock settings and update stuff. I can’t remember that ever not working. It feels like a low-key arms race, in a cold-war kind of way
