Another reason might be jealousy. If a character in the fanfic is trying to do something related to Harry Potter, like write a book about him or start a movement in his name, others who are jealous of their potential success could send rejection letters to thwart their efforts.
The Harry Potter rejection letters in fanfic could be a creative way to explore alternative storylines. For example, if Harry himself received rejection letters from potential allies or organizations in the wizarding world, it could lead to him having to find other ways to achieve his goals. It could also show how the wizarding world isn't always as accepting as it seems, and there are bureaucratic or personal reasons for rejections.
In fanfiction, Harry Potter rejection letters can be a fascinating aspect. They might be letters rejecting Harry from certain opportunities within the wizarding world. For example, he could be rejected from a special magical club or a scholarship. These rejection letters add depth to the story by showing that even the 'Chosen One' isn't immune to setbacks.
One common theme is the idea of being an outsider. Harry already feels like an outsider in the wizarding world at times, and a rejection letter can emphasize this. Another theme could be unfairness. The letter might be a result of some sort of prejudice or misinformation within the wizarding community.
Sasuke might believe that he's a danger to Sakura. Given his associations with dangerous elements and his own dark powers, he may feel that getting close to Sakura would put her in harm's way. Therefore, he rejects her to protect her. This is a common theme in many fanfics where Sasuke is portrayed as having a strong sense of self - sacrifice when it comes to Sakura.
One reason could be the strict control by the official copyright holders. They might be worried about fanfic diluting the official brand or misinterpreting the original story. Another factor could be some fans' purist view. They only want to stick to the original works by J.K. Rowling and consider fanfic as something not in line with the 'true' Harry Potter universe.
One possible reason could be Snape's long - held grudges and resentments. He has a complex history with Harry's father, James Potter. Snape might see too much of James in Harry and be unable to separate the two, thus rejecting Harry despite any potential father - son connection. Another reason could be Snape's own self - loathing and his belief that he is not worthy or fit to be a father figure. He may think that he would only bring harm or a bad influence to Harry's life.
One possible reason could be extreme despair. Maybe in that fanfic's alternate universe, Harry has lost all his friends and loved ones in a very tragic way, like a second wizarding war that was far more brutal and unforgiving. He might see no way out of the emotional pain and thus choose to end his own life.
It could also be that the fanfic might interfere with the way he wants his story to be remembered. His adventures at Hogwarts were real and important to him, and when fanfic changes the narrative, it's like his story is being disrespected. For example, if a fanfic portrays him as cowardly when he was actually brave, that would surely make him dislike it.
One reason could be a personal betrayal. Maybe a close friend from Gryffindor betrays Harry, and this makes him start to dislike the whole house. It's like when one bad apple spoils the bunch in his eyes.
One possible reason could be extreme depression. Maybe in the fanfic, Harry Potter has faced so many losses and hardships that he feels there's no way out. For example, if he lost all his friends and felt alone in the fight against dark forces, it could push him to such a dark place.
