illegal uploading/reading controversy

now that mangago is once again under fire by korean authors, i just have a question. i think the authors are completely justified in wanting their work removed, but i'm just wondering why i never see this energy directed towards korean websites like toonkor, newtoki, etc. like are they also targeting those websites and im not seeing it or are they just not aware/dont care or somethin? i dont really keep up with their twitter accounts so maybe i've just missed it but i wanted to know if anyone else was wondering the same thing
