I think I can finally end my ongoing diatribe against YT advertising. For some reason they keep sending me adverts for Korea, I think it must be part of a wider campaign, not just the algorithms targeting me based on my previous interests.
I ended up watching a full advert, then clicking on the site, which is kind of brilliant and is, temporarily at least, added to my favourites. I have no intention of visiting Korea but I do enjoy the music. And the dancing.
