Never heard of this myself... but the algorithm doesn't present you with content based on you watching the video but though others that are highly correlated with you. Maybe you started watching some weird fringe video channel that somewhat mirrors your habits but is also highly linked to viewers of these other things? The algo is just going to start grouping you into these groups if you like it or not. Don't like it? You can always do an rng spin of all posted videos and hope to find something you like, or just cut out your weirdly correlated video watching preferences.
