One reason could be that it's a self - indulgent piece. The writer is creating it just for their own enjoyment and doesn't want others to judge or interfere. So they think nobody else needs to know.
Well, it could mean that this fanfic about Cloud and Sora is something private or not meant to be widely known. Maybe it contains some personal interpretations or storylines that the creator wants to keep within a small group or just for themselves.
One reason could be bad writing. If the grammar, spelling, and overall style of the fanfiction are poor, it can make it unreadable and thus no one can stand it.
Someone might say 'no reading fanfic' because they are focused on the original source material. Fanfic can deviate a lot from the original, and they might not want to risk getting a distorted view of the story they love. Also, they could be concerned about the legality or ethics of some fanfic, especially if it seems to be misusing the original work's concepts.
Perhaps it's used to show a moment of extreme rejection or isolation for the person. Maybe they've lost their way or made a series of bad choices that have pushed others away.
They might have read a bunch of crossover fanfics that were just really bad. For example, the plot didn't make sense or the characters' personalities were all wrong.
Someone might say it if they think Naruto has evolved into something more than just a ninja - based story. For example, it has complex character relationships that are not just about ninja battles.
Maybe because Naruto has a large and diverse world - building. It's not just about the Uzumaki. There are other important clans like the Uchiha too.
One reason could be that novels are open - ended. There's no one definitive way to read them. Different people might focus on different characters, plotlines, or themes, so no one can claim to know the one and only 'truth' about the novel.
Maybe they just don't understand the real essence of Harry Potter. They might have only seen a small part of it or misinterpreted some of the more emotional or character - developing moments as signs of weakness, which is completely wrong.
They might feel that the flood of fanfic is diluting the true nature of the Naruto story. There are so many different interpretations in fanfics that it could be confusing or detracting from the core of what Naruto is all about. Also, if someone is more of a purist about the original Naruto series, seeing so much fan - made stuff might make them feel that enough is enough.
