In some fanfictions, Harry's scar might hurt because of dark magic remnants. Maybe there are leftover spells from Voldemort that still linger and cause pain. It could also be a sign of a new threat emerging, like a hidden follower of Voldemort trying to use dark magic in a new way that affects Harry through his scar.
Well, his scar could hurt in fanfiction due to magical interference. For example, if someone is trying to access his mind through the connection that the scar represents. Or perhaps a new, powerful magical artifact has been unearthed that has some sort of link to Voldemort and is causing the scar to act up. Another reason could be that Harry is unknowingly getting close to a place filled with strong dark magic, and his scar is reacting to it as a warning.
Well, he might become more cunning and calculating. Maybe he starts to use more devious means to achieve his goals, like Scar from 'The Lion King' who was always plotting. He could also become more self - centered and less concerned about the well - being of others around him.
It could be that Harry reads Harry Potter fanfiction to feel more connected to his fans. By reading what they write, he gets a sense of how they view him and his friends. He might also find comfort in the fact that his story has inspired so many people to create their own tales within the same universe. Fanfiction can be a form of flattery, and Harry might enjoy seeing how much his story has captured the imaginations of others.
Well, it might lead to Harry having to isolate himself. If the pain is severe and constant, he may not be able to function normally in his daily life at Hogwarts or in the wizarding world. He could also become a target for those who want to use his pain for their own gain. For example, someone might try to blackmail him or use his vulnerability to get access to secrets he knows. And if the scar hurting is a sign of a new threat, it could put all his friends and the entire wizarding world in danger again.
It could be due to the trauma he has experienced. Losing friends and facing Voldemort multiple times has surely left deep scars. Isolating himself might be his way of dealing with the post - trauma stress. He needs time alone to heal and come to terms with everything that has happened.
It could be that someone did something really wrong and Harry needed to express his strong feelings in a very public and intense way. Howlers are notorious for being attention-grabbing and forceful.
Maybe she's trying to get his attention or has something important to tell him.
Also, legal issues play a role. There may be laws and regulations regarding intellectual property that the 'Harry Potter' owners are following. By banning fanfiction, they are ensuring that their intellectual property is protected and that no one is misusing or misappropriating the concepts, characters, and world they have created.
Well, in some cases, the quality of fanfiction varies greatly. There might be a lot of poorly written fanfictions out there that use the Harry Potter name just for popularity. These might have bad grammar, inconsistent characterizations, and illogical plots, which can make the whole idea of fanfiction based on Harry Potter seem annoying.
Fanfiction starting with Harry Potter could be due to several reasons. Maybe it's the rich magical world that offers endless possibilities for new stories. Or, it could be the strong fan base and the desire to explore different scenarios for the characters.
It could be that Dumbledore has some strategic or protective reasons. Maybe the electives Harry chose initially could expose him to greater risks or prevent him from developing crucial skills needed later on.
