The magazine Story Club: The shadow of the post-90s childhood, why was the content 20 years ago "unsightly"?

Because in addition to some jokes, there are some stories that are very similar to bosom friends, and all the stories written to attract attention are more than enough, which are not suitable for minors. I remember a story I read when I was a child, which is still impressive. The general content is about the story of rich people eating human milk themselves in order to find a wet nurse to feed their children. For a young me, is it really unbearable lightness in life?
