I don't know how these things get to be advertisements. An explanation for the weird content might be people trying to build up watch hours to get the 4k hours requirement for monetizing their channel. I know a bunch of SE Asian people who are obsessed with this. They have channels where they just ramble on for hours, building watch time. Then they form groups where they help each other by taking turns watching each other's rambling. Crazy world.
