I get to play this YouTube game with students every time me or one of them play a clip as part of a presentation, assuming we're logged in (and we often are, as students and myself use Google Drive).
For me, I simply reveal my love of video games (and since having kids, slews of kid music) but for them it's a wild mix of ASMR, make up videos, musical tastes, and so on. Nothing too crazy yet, but its only a matter of time.
I'm grateful I at least have the foresight to use burner accounts for things like watching cringy movies (I listen to podcasts that make fun of them, so that's a thing). It'd be pretty funny if something like Pandemic 3 popped up in my feed, haha.
Somehow YouTube seems to be filtering out all the videos I play for my kid from my recommended page. I'm not complaining, but I'm surprised that it recognizes that I'm not going to choose that myself on an impulse.
