Inappropriate fanfiction like this can distort the perception of the characters. Harry Potter and the other characters are symbols of positive values in the series. When such inappropriate relationships are created in fanfiction, it can mislead new fans or those who are not familiar with the series, making them think that the series has such improper elements, which is far from the truth.
It can drive away a lot of fans who respect the original values of the series. Many fans love the series for its positive themes and this kind of inappropriate content is a big turn - off.
One negative impact is that it may drive away younger fans. Since 'Harry Potter' has a large base of young fans, when they encounter such sexualized fanfiction, it might make them feel uncomfortable or even disgusted, causing them to distance themselves from the fandom. Also, it can make the fandom seem less family - friendly, which was one of the main attractions of the original series.
Well, it can damage the reputation of the overall 'Harry Potter' fandom. The original books are known for their positive values like friendship, courage, and the fight against evil. When sex magic fanfictions exist, it may give the wrong impression to outsiders that the fandom is about inappropriate and adult - only content, rather than the magical world that J.K. Rowling created for everyone to enjoy.
It can corrupt the image of the fandom. The Harry Potter fandom is known for its love of the magical world, the characters, and the positive values. 'Sex magic' fanfic can make the fandom seem inappropriate and drive away many fans who cherish the original spirit.
Well, it can drive away many of the core fans who love the original series for its positive values. These types of fanfics introduce elements that are not in harmony with the original themes of magic, friendship, and courage. They can also create a negative image of the fandom in the public eye, making it seem like a place that tolerates inappropriate content instead of celebrating the magic of 'Harry Potter'.
It can alienate a large portion of the fandom. Since the Harry Potter series has a broad audience including many young fans, sexy fanfiction can make them feel uncomfortable or excluded. It also may distort the original image of the story and characters.
It gives the fandom a bad reputation. The 'Harry Potter' series has a global following and is associated with positive things. Fanfiction like this makes the whole fandom seem seedy and inappropriate, which is unfair to the vast majority of fans who engage in positive and respectful fan activities, such as creating art, writing proper fanfiction about the characters' adventures or relationships within the appropriate context of the story.
It can turn away many fans, especially those who want to keep the purity of the 'Harry Potter' world. When such vulgar fanfiction exists, it makes people feel that the fandom is not a positive and clean place anymore. This kind of content also goes against the values that the original series promotes, like friendship, courage and love. And it might make some people, especially parents, reluctant to let their children be part of the 'Harry Potter' fandom.
Definitely not. The Harry Potter series is about magic, friendship, and heroism. Fanfiction should be based on expanding these positive themes rather than creating inappropriate and offensive scenarios. This kind of content also disrespects the original work and the author's intentions.
One negative impact is that it violates the ethical and moral boundaries. It promotes a wrong and vulgar view of relationships, which is not suitable for the general audience, especially younger fans who grew up with the Harry Potter story. Also, it can create a negative environment in the fan community, discouraging positive and healthy fan creations.
