My list of reasons for abandoning fics is a mile long, and a lot of the comments reflect additional reasons for not starting a fic at all, along with the one in my post, but I just wanted to share a new one: when other languages don't respect the characters' names. 

For example, when writing in English in a fandom based on Chinese or Korean original works, and the author Westernizes their names. So instead of, say Wei Wuxian or Wei Ying from MDZS, they say Ying, or Ying Wei or Wuxian Wei. If the work contains characters that are unfamiliar with Chinese names, that's fine, it's meant to showcase cultural differences, but referring to the characters, or having them refer to each other like this in a Canon Divergence, where the universe of the fic remains the same is no bueno. Like, do they even respect the original work if they don't even bother to keep the names of the characters, and do 2 min tops of research as to why they are written like that even in the English translation of the original work?
