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.
I think this is pretty much what it boils down to. Where do you draw the line between having the right to expose yourself to media that validates your world view and this media becoming a threat to you to a point where you require intervention?
I've seen lots of people discussion their family's Qanon casualties to recognize it's a legitimate problem, not to mention tragic in many cases, but I would still think twice before 'tricking' someone. What if she realizes what's happening and becomes more radicalized by this? I find that direct conversation, discussion, and confrontation work better; or at least that worked with family that believes in bullshit.
That being said, the harmful effects of being trapped in a bubble by an algorithm are not largely disputed.
