ppl used to reupload official chapters cuz the names were super different but recent manhwas typically have the same name for unofficial and official chapters
i guess they just reupload out of habit now?
Do you mean the name of characters or the title?
Sometimes quality of some unofficial translation is bad or some has bad cropping
Unofficial translations or self translations specially google trans ones changes the dialouges making it confusing to read and has grammar errors. The quality is bad sometimes. But I do love translators that translates for the stories no hate on them.
Why post the official chapters when theres already chapters from scan/translator group? I mean the translation is not that different, why the need to post the official ones?
