Well, it's not acceptable. Fanfic should be a creative and positive exploration of the source material. Sexual content like that not only goes against the family - friendly nature of many fandoms but also may objectify the characters. We should encourage fan works that promote positive values, such as those that explore the characters' growth, their relationships in a non - sexual way, and their contributions to the fictional world.
No. Fanfics involving sexual content are not appropriate in most fan communities. They violate the ethics and moral standards, and may also go against the rules of many platforms. Such content can make other fans uncomfortable and can have a negative impact on the overall positive and creative fan culture.
