There's fueling political and social rage with "news", casting doubts on family relations with "true life stories" (daughter-in-law threw me out of my house), religious "coaching" (dead since end of 60s Padre Pio gives you life lessons and "secret" prophecies), worthless tips and tricks (don't eat this nut if you're 50yo woman or your hair will fell off), lewd promotion with twist on history (sexual violence in every thumbnail) or tourism (women in country of x are "ready" all the time). So on and so on.
So I'd say it's not that much strange if you look closely what kind of the content older people can walk onto. And this is just youtube.
