I'm the member of the Admin Team who took down the story. The story didn't flat-out break any rules here regarding minors involved in someones story-telling.
But in my judgement it came too close for comfort. Not because the entire story was predicated on an abusive situation, but specifically because...you had an over-18 male physically touching an underage female on the pelvic region. Too close for comfort, so I "erred on the side of caution" in regards to protecting this website & its membership.
Did I overreact? Possibly. I invite you to contact the site owner directly and spell this all out for him ( including this post from me) and see what he says. It's his webbsite & rules, not mine , so I'll abide by whatever decision he makes. That being said...I "permanently deleted" the story, so I don't know if it's even recoverable. If not, you'll have to re-post the whole thing again. Sorry.
