My web browser blocks all cookies and therefore no matter how often I visit YouTube, it thinks I'm a brand new user. The video recommendations I see are therefore YouTube's "default" set; presumably what's trending at the time.
The recommended videos are, without exception, pure trash. We're talking everything from Buzzfeed-level clickbait with blatantly Photoshopped thumbnails to the lowest-effort softcore-porn-level sensationalist crap which is mostly composed of lobotomised talking heads, mouths agog, "reacting" to other people's content.
Quite often YouTube presents starkly contrasting recommendations, for example a video of violent combat footage right next to some kids dancing, or stuff like this elegant pairing of the sexualisation of women next to some cUtE pUpPiEs: https://i.imgur.com/TcxhVhH.jpg
It's psychopathic.
