No, they don't need to recognize this manhwa more. The more attention a manhwa gets, the more people from this d*mb generation start posting about it all over soc*al med*a without thinking twice. That kind of exposure draws unwanted attention to s*tes like this one, which can lead to them being sh*t down—especially now that the K gov has been actively targeting them.
It can also affect the manhwa itself, as some auth*rs have discontinued their work after finding out it was being reposted and spread all over the internet...
Maybe consider the fallout before demanding more recognition.

People need to start recognizing this manhwa more
