I don't and won't often do this, but I'm going to call out an author.
E.F. Turner has stolen from authors. I know of many, including myself, who post at SOL and other sites. For an example, in her "Erotica Collection #9," she has plagiarized my entire story, Island Encounter, only changing the name of the lead character from John to Justin.
My story, Island Encounter, was posted on StoriesOnline.net in November 2010, as you can see on my submissions page. Her book was published in May of 2014, and it was hardly the only one stolen from authors. Please spread the word; if you recognize a story, please leave me a comment or if you can contact the author, do so. Most stories seem to be in the BDSM and Incest and Non-Consent categories.
I realize it's a risk you take on the internet, posting things for free, but I'm not going to let someone take advantage of me if I can help it.
This is her Facebook page; if you can post proof of stolen stories, please do. She's also on Goodreads. I'm not asking anyone - in fact, I explicitly ask that you don't - to bully or otherwise harass her. Pointing out the stolen stories is enough.
