Definitely not. These types of stories usually lack any real literary merit. They are more about titillating the reader with sexual details rather than providing any kind of profound insight. Good literature should be about exploring the human condition, society, and culture, not just about sexual fantasies. And such stories can also be offensive to many people, so they have no place in proper modern literature.
I'm not sure who this 'Douglas Smith' specifically is in relation to such inappropriate stories. There could be many people named Douglas Smith, and it's not ethical to promote or be associated with 'sex smut' content.
One way is to have strict community guidelines. Platforms that host fan fictions should clearly state what is acceptable and what isn't. For example, any explicit sexual content should be prohibited.
Well, it can have a negative impact. Such fan fictions often focus on inappropriate sexual content rather than on the positive aspects of the original work. It might divert the attention of readers from the real themes and values of the story. For example, if it's based on a fantasy series, instead of exploring the magic and adventure, people get distracted by the smutty parts.
They can have a negative influence on mental health. Constant exposure to such graphic sexual content might lead to desensitization to normal sexual relationships and could potentially cause problems like objectifying others. Also, it can contribute to the spread of an unhealthy sexual culture. Since these novels often present extreme or unrealistic sexual scenarios, it can mislead readers into thinking that such behavior is normal or acceptable in real - life relationships.
