at least with youtube, you can be quite defensive with what it's shoving down your throat.
turn off view history, so you don't see 100 toilet videos after watching a video on japanese toilets.
aggressively click "Don't show me this" in its video suggestions, whenever it strays towards politics or similar bait.
despite the inundation of slop, rage bait, and brain rot, youtube still has a goldmine of good content if you can defend yourself from the rest.
