No. 'Smut' typically refers to pornographic or vulgar content. Writing such content, especially in a fanfic context, is inappropriate as it goes against moral and ethical standards, and may also violate the rules of the fan community and potentially the law regarding the distribution of inappropriate materials.
The negative impacts are numerous. Firstly, it violates the ethical boundaries of creative writing. Fanfic is meant to be a celebration of the original work, not a platform for vulgarity. 'Pregnant smut fanfic' can also lead to the alienation of many fans. For example, younger fans or those with more conservative values will be put off by such content. Moreover, it can damage the reputation of the entire fanfic community as it gives the impression that it is a place for inappropriate and immoral content.
Well, a smut novel refers to a book where the focus is heavily on sexual themes and often has very detailed and graphic descriptions of sexual acts. It's not for everyone and is usually considered more adult-oriented.
Well, it depends. If it's just an occasional read for entertainment and the person can clearly distinguish between fantasy in the novels and real - life values, it might not be too harmful. But if it starts influencing one's behavior or attitudes towards others in a negative way, then it's not healthy. For example, some smut novels may promote objectification of people, which is not a good value to uphold.
There is a wide range of fanfics out there, and while some people might be interested in the so - called 'bella smut fanfics', many others prefer more positive and clean - cut stories. The popularity of such adult - themed fanfics is likely limited due to ethical and moral concerns among a large part of the fan community. Also, most official platforms have rules against overly sexual content.
