Yup. This isn't the first time I've heard a scan group ask people to stop. A year ago fans were tagging a groups twitter in tweets to a mangaka, and almost got the group shut down. Some people don't seem to understand the concept of fan translations at all.
They're probably huge fans of having being dicks.
They are indeed stupids.
What do they have inside their heads? Apparently nothing lol
Is it real that about people writing to mangakas and let them know that they are reading illegal work? What do they have inside their heads? Anyways, thank you for the update ヾ(☆▽☆)
