Unfortunately, the legitimacy of the story has no influence on its legitimacy on hubpages. For the most part, the filter system on hubpages is entirely robotic. So it can't distinguish the word 'sex' in an inappropriate article from the word 'sex' in a story or medical article. Therefore they all get nixed equally. To some degree, you can still post the article without advertisements, but it gets to a point where it isn't worth the battle. Erotica, in particular, would likely lose the ads first and be taken down later by administrators. It's sad, but true. You would be better off compiling your old stories and publishing them on amazon with your other stuff.
