There was a story like that featured on that website that makes fun of fanfiction, they really ripped into it. The author was quite rightly upset and removed her story from the internet. A friend pointed it out to me when we were talking about rare kinks and I thought it a shame she'd been harrassed like that. Was it one where Sherlock was given a lye enema that made him scream while unconcious? If so, that story is now long gone.
