Thanks for letting me know - I found that I can click a link and still get to it, so it’s not gone entirely at least? It is a smut story but definitely has both a plot and is way, way less than 50% porn. Idk, we’ll see I guess
Yes, they are not removed, just hidden, and only authors have access to them. It's so that if there was a mistake (those happen), everything can be reverted without a problem.
Also, no, there is no rule of "50%" porn; you misinterpreted it. It's basically "if there is only porn without a plot, that's not allowed." No one will check if you have 50% or more to swing that hammer; it's the content that matters.
