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.
In googles settings you can turn off watch history and nuke whats there, which should affect recommendations to a degree. I recommend you export her youtube subscriptions to people she likes (that arent qanon), set up an account on an invidious instance, and import those subs. This has the benefit of no ads and no tracking/algorithm making. The recommendations can be turned off too I think. Freetube for desktop and newpipe for andrioid are great 3rd party youtube scrapers. The youtube subs can also be imported to a RSS feed client.
If she watches on a laptop or PC you can change the icons to what she is used to using. Like if she uses Chrome browser you can switch Peertube ixon to a chrome icon so she click that one too.
On mobile newpipe is a good option too
