I am fond of videos showing people's trips in Antarctica. This tendency exposes me to flat-earth videos ALL THE TIME. No matter how many pleasant tourist videos I watch, I still get flat-earth videos and even occasional hollow-earth videos. (the flat earth view includes the notion that the Earth is a disk with Antarctica as the outer edge).

I can't watch the pleasant tourist videos of Antarctica before bed, in case I fall asleep and the automation shows me a stream of flat-earth videos.

The link here is just the word Antarctica. The flat-earth view has nothing to do with viewing penguins or pleasant scenery.
