In private communication: her original "The Keptverse is RPS" post was, according to this e-mail correspondence, apparently intended as a clear signal that writers attempting to do FPS in Keptverse should stop doing it.
While the basic plot, story, and structure of "The Games" was already clear to me at that point (though I'd originally imagined that I could deal with the whole series of events in "End-Game" and "In the Name of the Wolf" in seven 2000+ chapters) I hadn't yet got a clear picture of Greg or of the four girls. What I did have was an idea of a paraquel story about Wilson and Greg, and it was that story which, having been set aside as a story-in-itself given "The Games" was now going to be the only FPS Keptverse project, was the reason "The Cripple" got written instead of any other backstory. (Greg would still have shown up in the concluding chapters - I wanted another enslaved former doctor.)
It's an even more difficult situation when the author is in the same community as oneself.
I went on writing "The Games" despite having had it made personally clear that poisontaster would rather I had stopped short and let it go uncompleted, because ... I couldn't have stopped. I could have stopped sharing it, but ... the story by that time was there. The only way to get it out of my head was to finish writing it, and I wanted it out of my head.
In many ways it helps to be on IJ. Not that many people are going to read a long story which takes place in an AU to a fanfic universe, and especially not when it's on insanejournal. (All of the slavefic sites I know of are on LJ.) I'd be delighted if you reviewed it, and would perfectly understand if you decided not to, knowing what you now know, but in many ways I'm not in the same community of writers as poisontaster ... except in the broad sense that we both write fanfic.
Not that I feel this changed my ethical responsibility. There were other stories already being written in the Keptverse at the time I started constructing mine, or I would have written to ask specific permission: it no more occurred to me to ask "is FPS OK?" than it would have done to ask (if AKB had been het) "is slash OK?" But just as a fanfic writer of Pern slash may feel it's OK providing she doesn't push it under Anne McCaffrey's nose, so I tend to feel: well, it's not as if this story can become a major irritant to poisontaster - it's on IJ.
(who now gets to deal with the "am I borrowing too many fanfic tropes in my originalfic" issue)
I've always felt that borrowing tropes is OK - wherever you borrow them from. What I was clear with this story was that I wasn't "borrowing tropes" - I was deliberately writing fanfic in a fictional universe created by poisontaster.
