They mostly threaten to sue privately, they will ask the uploader/translator to take it down or face legal action. With Japanese authors, it's mostly their publishers who send the warning letters from what I've seen. With Chinese authors, legal action is harder I guess especially if the work contains smut (read about Chinese bl authors that got jailed), and they mostly use weibo, so most of them are not active on X. Koreans authors are definitely more outspoken on social media out of all of them I think.
The author of https://www.mangago.zone/read-manga/pink_heart_jam/ which is Mangaka talked about that and was planning to cancel her work over that https://x.com/futekiya/status/1342062543171420160
I mean, it's just that they weren't loud enough about the fact that they hated that. Euja was heard because she was direct, clear, and misunderstood about her words as threatening.
Some authors do nothing about it because they know that and powerless and that nothing will change. Euja is just taking all those frustrated emotions and throw them at our faces.
She's literally Kim Euihyun. She's works super hard, maybe wanting to quit (suicide like in the first chapter), but still getting poor because she's not paid enough so she have to work extra hard all the time. And just like her character, she's fed up by all that.
Oh yeah I think I remember this incident
hey so this is crazy
Like batshit crazy
I have a question tho. Why is it always Korean bl authors crashing out over piracy of their work. I have never seen Japanese mangakas whether bl or straight, Chinese authors whether bl or straight lose their shit over it. Heck even Korean manhwas that draw straight romance don't go crazy over piracy or their works being shared on illegal site. It's always Korean bl author. It's so strange
