Welcome to the community 
I hate to say this, but I actually think that they have a better chance to get noticed if they stick with what is already popular. I‘m pretty sure I’ve seen more small authors take off with overused plots, than others with really unique ones 
Original concepts might be appreciated more I’ve seen 5 paragraph long fanmail for certain stories, but never for cliche ones, but unfortunately they usually attract a smaller audience.
It’s not the same because the reads dropped overall, but it’s possible. And it’s possible with a non-cliche story too, but less likely. I’ve seen examples for both.
I think the people on the forums mostly think like this, but we are only a small part of the community. As @ColeCatalyst mentioned, many others want to read about sex. I’m pretty excited to see what will happen when Ivy goes live, because I low key hope that this trend will move there, and something new will start on Episode.
But then again, I’m worried about this:
Because if it’s really mainly the young readers who read these stories, then nothing will change and there’s no point in creating the mature app. Unless these young readers will figure out a way to use it, which I hope they won’t
