This partly explains why the recommendations I receive don't feel like mine. Multiple times, it's been obvious that the suggestions were pulled from other profiles and I could even tell whose.

My hypothesis

* The algorithms have linked my account to some others.

* They then serve me the embeddings extracted from those profiles. The near-real-time nature of this has crossed my mind more than once.

It's really unsettling, and afterwards I feel uneasy about any recommendations (all Google services, Netflix seems problematic too, not Amazon).

YouTube seems to have some hidden knobs for tuning this behaviour: after multiple negative feedbacks, the problematic content disappeared from my front page. However, the recommendations on the right-hand side of individual videos remain problematic, and the automatic playlists of YouTube Music are still strangely disturbing (even after multiple negative feedbacks).
