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.
The large and detailed cast of characters. There are so many characters in Harry Potter with their own personalities, backstories, and relationships. Fanfiction writers may struggle to keep all these elements in mind and might find it annoying when trying to incorporate them into their own stories without making mistakes or contradictions.
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.
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.
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.
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.
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 he's looking for inspiration. The rich world of Harry Potter can spark all kinds of creative ideas, and fanfiction can be a great source of inspiration for his own writing or just for daydreaming about the wizarding world.
One reason could be that Harry Potter is the main character of the series. His story arc is central, and Snape is often a complex figure in relation to Harry. Writers might be more interested in exploring how Harry's actions and growth impact Snape's character and vice versa. Also, Harry has a broader range of relationships within the wizarding world that can be intertwined with Snape's story in fanfiction.
The dominance of Harry Potter in Marietta fanfiction can be attributed to multiple factors. Firstly, the Harry Potter series has a huge fan base, and many fans are more interested in stories that are closely related to the main plot which revolves around Harry. Marietta is a relatively minor character compared to Harry. Secondly, the world - building in the series is so comprehensive that it's difficult to write about Marietta without referring to the broader context of Harry Potter. For instance, the magical laws, Hogwarts' structure, and the ongoing battle against Voldemort all have a connection to Harry. Fanfiction writers may unconsciously or deliberately use Harry's character and his story to add depth and significance to Marietta - centric stories, which results in Harry Potter's domination in such fanfictions.
In some fanfictions, Dumbledore might bow out of respect for a powerful magical entity or a person with extraordinary abilities. It could also be a sign of his humility in the face of a situation where he realizes he is not the most knowledgeable or powerful.
