Your mum is 70. As far as you're concerned, you're her Guardian now. Block that shit and put old NatGeo specials on repeat. "Old" because the current NatGeo is shitty Yank Trucker Alien Tuna Trash. You must treat her like a child who needs guidance and fresh air. Limit the tv and internet to 3 hours a day. Make her spend daytime hours socializing irl with pensioners club etc.

Clearing youtube history and personal ads may help not sure though

It's not going to be easy. most likely she'll be exposed to this shit elsewhere too, not only on youtube. fully reset the browser in ANY case. delete history, cookies, everything.

besides that, I see multiple options. you can consider them all or in various combinations

• completely block youtube (for example via hosts)

• new account

• unsubscribe from everything

• reset/delete watch history

• https://myadcenter.google.com/personalizationoff?hl=en

  • disable personalized adds
  • from there go to the "my activiy"
  • https://myactivity.google.com/page?page=my_ad_center_preferences&pli=1
  • delete all

• enable restricted mode (essentially making it a kids account)

• change location/region of the account

• go here: https://myaccount.google.com/u/0/yourdata/youtube?hl=en&pli=1

  • disable watch history
  • disable search history

If you're keeping the channel, the "Don't recommend this" method while also deleting watch history with controversial content would help. but honestly, closing the account and opening a new one with a fresh recommendation slate is the way.

Replace her existing account with a new one. Make up some excuse. Use the don't recommend channel option when a bad recommendation comes up.

Invidious or Freetube if she's on a personal computer.

Could also help to deactivate the personalized advertising functionality in the Google/YouTube settings (basically wipe currently stored preference, the forbid YouTube from making suggestions based on your interests). This will keep her feed fairly generic (and bad, oh boy) so that she would have to actively search for or subscribe to these videos.

You can go into the view history and remove all the bad videos.

My mom has a similar problem with animal videos. She likes watching farm videos where sometimes there's animals giving birth... And those videos completely ruin the algorithm. After that she only gets animals having sex, and the animal fighting and killing eachother.

block youtube/facebook/and any social media . though dns .with pihole for the time being . and in the meantime try to reset her youtube(or delete and create new one -if she doesnt use gmail)

accept her right to freedom of information

Get your mom on bondi rescue. She will never watch anything again in her life

Next to deleting, you can enable the option to automatically delete it every 3 months.

Google account -> Data & privacy -> History Settings -> YouTube History -> auto-delete

But, the best is to have a new account.

Redirect youtube to an invidious instance by editing hosts file

No joke, the answer is for her to stop watching YouTube. I drastically reduced my YouTube consumption from like multiple hours a day to max 30 minutes. The algorithm takes into account how many hours you've watched per day.

Idk on here, but if you need help on reddit there is a sub called Qanoncasualties and it's basically a support group for family members with Q whoevers.

In addition to deleting history, could you get direct access to the account and watch better/different content to hopefully get that stuff more recommended too?

Find several wholesome channels that have a decent amount of content and look at the playlists. Make sure auto play is on and just plow through playlist after playlist ever night.

I did this by mistake once with kid videos. Iy wreaked my feed for so long 🤣
