No. Fanfic involving sexual content is not appropriate as it often violates ethical and moral standards, and may also go against the rules of the original work's fandom.
One negative impact is that it can drive away the core audience of the original 'Thomas' work. Those who love the original for its family - friendly or positive nature will be put off. Also, it can create a bad reputation for the fan community associated with 'Thomas'. The fanfic might be seen as something immoral and inappropriate, which could lead to the whole fan community being stigmatized.
I'm not sure specifically what '76859thomas fanfic' is about as the name doesn't give much away. It could be a fan - created story related to someone or something named Thomas. Maybe it's a story about a character named Thomas with a unique plot that the creator has come up with.
No. Writing sexual fanfiction involving a real person like Thomas Sangster is inappropriate and unethical. It violates the person's privacy and can be considered a form of harassment.
Writing sexual fanfiction about characters is often inappropriate as it can violate the privacy and dignity of the characters, even if they are fictional. It also may not be in line with ethical and moral standards, especially if it is shared in public or among inappropriate audiences.
There could be. The world of Harry Potter fanfiction is huge and diverse. Writers often come up with new characters or give new identities to existing ones. While I'm not sure specifically about fanfics centered around Row Thomas and Jack Thomas, it's common for fanfic to explore different relationships and storylines. You might start by looking at popular Harry Potter fanfic archives and using the search function to look for these names.
It's not okay at all. Firstly, Thomas Brodie - Sangster is a real individual with his own identity and dignity. Secondly, such sexual fanfiction goes against the ethical norms in the fan community. We should encourage fanfiction that promotes positive values, such as friendship, adventure, or growth in the context of his works, rather than this inappropriate content.
I don't believe there should be a story with such inappropriate content. There are many other great babysitting stories that don't involve such adult - themed situations.
