RWBY fanfic writers can prevent abuse by following the canon as closely as possible. This means not making major changes to the established storylines and character arcs without good reason. For instance, if a character is known for being kind - hearted in the show, don't turn them into a cruel villain in the fanfic without proper backstory. Also, be cautious with shipping. Don't force characters into relationships that go against their nature or the overall tone of the RWBY world.
Writers of RWBY fanfic can avoid abuse in their stories by having a clear moral compass in their writing. Decide what values you want to promote in your fanfic, whether it's friendship, justice, or courage. Then, make sure all the actions and events in the story align with those values. Don't introduce elements that promote abuse, such as unfair power dynamics or immoral behavior without proper condemnation. By being conscious of the moral implications of their writing, writers can create non - abusive RWBY fanfics.
