Too much saturation of trash books has made it difficult for readers to identify which novel is actually good. I remember that I used to read a lot of translated novels when I first downloaded webnovel. Even original novels had geniune "originality" in them. But now, the same tropes are being used repeatedly and improperly.
These "authors" neither know about the basic thing about character design and world building, nor do they care to learn. Their grammar and punctuation is terrible as well. I get that they are newbies but if a writer isn't committed to finish his/her story, then why should they write? Why must they think of a stupidly large world, and write on it when they can't handle its scope? Why couldn't they write some short stories first?
Also, the over-sexualisation of characters is something concerning as well. It is fine if the story itself is rated 18+ and the author knows what s/he is doing. However, when new writers start by describing a character only by his or her body parts, their writing becomes hollow.
They would never learn to show a character's true trait, never know about the beautiful places that might lie in the worlds they've created, and never learn to critically think about their own writing.
As all experienced writers know, most of the webnovel readers are below 25 years of age. Their worldview isn't ripe yet. Fantasy is THE major genre covering almost 80% of the stories here, I think. In this genre, anything goes and readers as well as writers quickly forget about the things that are uncommon in real life. They would be negatively influenced by such types of stories, especially when most writers don't even care to warn their readers. How many of you seriously thought about those options where it said, "General Audience", "Parental Guidance Suggested", etc when publishing a new story?
Writing affects people as much as speaking does. Be aware of what you write and who your readers are. Give a heads-up if something gory, sexual, or psychologically impactful thing is about to happen. You should be able to do that if you can fill your stories with fillers for more $$.
