I believe doing a good translation was the translators responsibility. Also, are you not the one commenting very rude things on politely worded negative reviews?
This might be rude because your statement is ridiculous. You also pointed out that no one else can do the translation now that they volunteered, and it’s not truth. It’s not like it’s official, you could always contact Mazu if you want to propose ur translation, there’s literally no problem in that. It’s just that you decide to write paragraphs about how “poor” this translation was made and that this “disrespects the author’s writing.
