It could be anything from solving a magical mystery to getting into some unexpected trouble. It really depends on the specific fanfiction.
Well, it could be all sorts of things. Maybe he's discovered a new spell or faced a challenging magical creature.
It's an opinion. Fanfiction is a very fluid and creative area. There's no definitive end to it. Even if a lot of fanfiction has been written, there are always new ways to approach the characters, settings, and themes of Harry Potter. It's not like there's a set number of stories that can be written, and just because someone feels it's 'done' doesn't make it so in the overall scope of the fanfiction world.
In my opinion, 'harry potter is done fanfiction' can be understood in different ways. On one hand, it could indicate that the fanfiction community has explored all the common themes and plotlines related to Harry Potter. For example, we've seen fanfictions about the characters' further adventures after the books ended, their relationships in different scenarios, and what - if stories. On the other hand, it might also mean that from a creative perspective, new fanfictions are not being produced as frequently or with as much enthusiasm as before. This could be due to the fact that the initial hype around the series has died down a bit, or that the most obvious and appealing ideas for fanfictions have already been written.
Perhaps it implies that the essence of Harry Potter's story in the canonical works is complete, and there's no need for more fictional fighting scenarios as seen in fanfiction. The official narrative has run its course, and fanfiction's fighting - related ideas are now redundant.
Hermione could be a main character. She might use her vast knowledge to help Harry and Dumbledore in their adventures. For example, she could research ancient spells or potions that are crucial for their mission.
The first step could be better moderation on fanfiction platforms. They should have clear rules against such inappropriate portrayals. If they see any slutty Ginny fanfiction, they can remove it.
One reason could be that they feel the official Harry Potter story has a defined end, and the fighting in fanfiction is just over - done. They want to focus on the original tale's conclusion.
If there are such claims, the first step should be to thoroughly analyze both works. Look at the core concepts, character development, and plot structures. If it turns out to be baseless, which is likely in this case, then those making the claims should be informed about the differences between the two works.
He could simply stop reading it. If it's making him frustrated or fed up, the easiest solution is to just avoid it altogether.
One way to fix past mistakes in Harry Potter fanfiction could be by having a time - turner like device be used in a more creative way. For example, a character could go back and prevent certain tragedies like Sirius Black's death. They could warn him about the events that led to his downfall and change the course of the story.
