She's almost 70, spend all day watching q-anon style of videos (but in Spanish) and every day she's anguished about something new, last week was asking us to start digging a nuclear shelter because Russia was dropped a nuclear bomb over Ukraine. Before that she was begging us to install reinforced doors because the indigenous population were about to invade the cities and kill everyone with poisonous arrows. I have access to her YouTube account and I'm trying to unsubscribe and report the videos, but the reccomended videos keep feeding her more crazy shit.
First unsub from worst channels and report a few of the worst channels in general feed with "Don't show me this anymore". Then go into actual Google profile settings, not just YouTube. Delete and Pause/Off Watch History and even web history. It will still eventually creep back up, but temp relief.
