If they do that they should get rid of everything that has R-18 content, including their novels. FL novels will be basically excluded, as there are scenes of lingerie and provocations in the R-18 environment. And on top of that it will take a grand part of the range of writers and readers, probably grand part will migrate to the RoyalRoad.
And if they want to remove these contents, why not remove their novels, which have constant rapes from the FL's, that the purpose already has a community that highly criticizes this type of content. If we went because it was improper, I believe that novels with rape on the webnovel are much worse than CONSENSUAL novels that are R-18.
