Now I'm actually curious what the real story is, there's something happening here, but it's pretty clearly just being used as propaganda in this article.

The cop saying "you should have known you'd get in trouble for publishing this" should make it pretty obvious that whatever they were publishing specifically is likely very different from the standard "Boy Love" genre.

I'm kinda leaning towards the content in question containing explicit stories about young boys, but without the police reports or source material we can't know

Edit: Here's clip from that first article she links

It is worth noting that in the past, those who dared to try out such "sensitive" TV series were small-time actors who were neither famous nor famous, but now the gay dramas have gathered famous actors and big productions. Industry researchers believe that the entry of leading companies and leading artists indicates that gay culture is moving from subculture to the public eye, and these signals are milestone events in the history of the development of domestic gay culture.

"Male-male CP (pairing)" and "male sex economy" are new themes in the entertainment market. Now "selling homosexuality" has become a common phenomenon in the industry. The so-called "selling homosexuality" means selling "rotten culture", and "rotten culture" refers to a subculture that is fantasized by the audience and is between men, with ambiguous or love stories as the main content.

In recent years, the academic community has paid attention to and studied the impact of danmei culture on the gender cognition, marriage and love views of young people. For example, the article "Analysis of the Current Status and Influencing Factors of Sexual Identity of Some Adolescents in Hunan Province" surveyed the sexual identity of 1,260 adolescents in the province and found that 2.9% of boys considered themselves homosexual, 4.9% considered themselves bisexual, and 12.4% were uncertain about their sexual identity; for girls, the proportions were 2.4%, 12.4%, and 14.3%, respectively. 37.5% of people knew about "danmei" or "fan fiction", of which 32.3% said they "liked" it, and 11.9% said they admired the same-sex love described in literary works.

I think what's happening here is that the "Rotten Culture" is being conflated with homosexuality in general. I'm not sure exactly what the subgenre is, but it seems like it's more about pornographic material than anything. If homosexuality was so condemned, I don't think you'd have a massive industry rush to invest tons of money into gay focused media. You definitely wouldn't have almost 25% of young people respond that there either gay, bi, or unsure if there was serious consequences to saying that.
