Author seems like a really weird person.
First, he or she complains about the translation, and that people can access it w/o anyone paying, but in the second message, he says he wouldnt have paid a mind if everyone thanked the comic creator, not the translator.
If author knows English or something like that, and if he is reading this, I respect your decision, but this was a stupid idea, and its not going to help you in the long run. Your argument in second note is way more annoying than the first one. IDK man, if you wanna go this route go ahead, just know that people dont forget stuff, some people ask me about stuff I did like 7-8 years ago, this will end up as a stigma if you plan on getting licensed outside or smth with a different work
Good luck in life, best wishes
