I had to never turn my PS2 off or switch games because my mother didn’t understand the importance of a memory card. After the PS3 came out I had a used one that I got cheap but eventually ended up getting a PS3 myself instead of buying a second card.
I have it disabled too and most of my recommendations are the same. I have seen those same exact videos recommended and you can’t block them on the YouTube app. Default YouTube for anyone without defined history is constantly pushing these videos.
