Perhaps the fanfiction doesn't respect the world - building of the Naruto universe. Naruto has a deep connection to his world, from the hidden villages to the different jutsu. If the fanfiction messes with these fundamental aspects, for example, by creating new and illogical rules for chakra or changing the relationships between the villages in a wrong way, Naruto would not accept it as it goes against what he knows and loves about his world.
Well, Naruto has his own journey and story arc in the original Naruto series. The 'cra fanfiction' might deviate too much from what he has experienced and learned. He has grown up with certain beliefs and goals, and if the fanfiction doesn't respect those, he'll refuse it. Additionally, he might be concerned about how such a fanfiction could influence the perception of his friends and the village he loves. If it portrays them in a negative or inaccurate light, he would surely stay away from it.
The fanfiction could be presenting a version of Naruto that doesn't align with the canon. In the official Naruto story, he has a specific growth arc and personality traits. If the 'cra fanfiction' changes these too much, it's like creating a different character altogether. Naruto, as we know him from the original, would not be part of such a misrepresentation.
One reason could be that Naruto has his own independent goals. He's always been determined to become Hokage. Maybe the team's goals don't align with his. For example, if the team is more focused on short - term missions for money rather than long - term village development like Naruto wants.
Maybe the fanfic was too far - fetched from the newly revealed heritage. If the CRA wants to keep the Naruto universe consistent, a fanfic that goes against the fresh revelations about Naruto's heritage would be refused.
One possible reason could be that Naruto wants to develop his own unique ninja way without relying on the traditional toad contract. He might feel that it would limit his growth in a sense.
In some fanfictions, his family might be involved in dark magic or have a bad reputation. So, Harry Potter refuses them to uphold his own moral values. He is known for his strong sense of right and wrong, and if his family goes against that, he would distance himself.
One reason could be that some fans are very purist about the original Naruto story. They might feel that fanfiction often distorts the characters or the plot in ways that go against the essence of what Naruto is all about. For example, changing a character's personality completely to fit a romantic or dark and edgy narrative that doesn't align with the source material.
There are several possible reasons. For one, it could be a way to subvert the expectations of the Naruto character. In the original series, he's so pure and full of life. By having him smoke in fanfiction, writers can create a contrast. It might also be used to set a certain mood, like a gritty or more adult - oriented atmosphere. Additionally, it could be a symbol of his rebellion or a sign of him breaking away from the norms of his ninja village. Writers might use it to explore a different side of Naruto that wasn't shown in the original story.
One reason could be the waning popularity of the Naruto franchise over time. As new shows and series emerge, some fans shift their attention away. Another factor might be that the quality of fanfiction has declined. With so many people writing, there's a lot of poorly written stuff that turns readers off.
One reason could be to explore a different character arc. Writers might want to see how Naruto would develop if he had a more violent nature from the start. Another reason is to add drama. A bloodthirsty Naruto would create more conflict within the story, especially with his friends and the village. Also, it could be a way to show a more 'realistic' or gritty version of the Naruto world, where characters are not always so morally upright.
