Ah yeah I've heard it can send you into a spiral if you aren't careful. I get pop ups from time to time but I think the algorithm knows exactly what I like now. I mainly get food videos, science, cute animals, gundam, gunpla and crafting, travel, video games, anime and streamers lol. I guess it's just visual junk food.

Anything political, or news related I avoid and spam the "don't show me this" button lol. It's really weird seeing the main page of youtube when you're not logged in. It's so different!
