I suspect most people aren't subbing/following communities on Lemmy. So post the community or topic you want to see pop off. And reader(that's you) if you are interested in that community click the link and follow it.
Regardless of style “web novel” and “light novel” aren’t specific to a source country like manga and manwha are.
Both Wikipedia and Wiktionary define them as Japanese. The same goes for the original Reddit community or the database the bot (Myne) gets her info from. I did not take down your comment (it's still up) but pointed out that it's the wrong community for that reason. I didn't do it on a whim.
I'm not categorically against Korean (or Chinese) novels, but they're by every definition I know simply not "light novels". I believe that a general book community would be a better place to discuss other translated works. For reference, the place on Reddit to post Korean Webnovels would be r/noveltranslations instead of r/lightnovels.
