I run https://fiction.live https://fiction.live which has a similar recommendations function as youtube. The key insight here is that dislikes are not the same thing as uninterested. People will dislike stories that they're interested in but think are poorly written or do not have the ending that they want it to have. If you use dislike to mean uninterested you are ruining the recommendations. Rather you need to have a separate button that says do not recommend other content like this. That's what we do and it works out well.
