I've spoken from a very emotional standpoint on the matter in question, and I stand by my judgment. However, that said, there's no utility in venting my spleen and making it impossible for someone to make amends in the future. That does, of course, assume that the person involved sees a need to make amends. I have my doubts that anyone implicated has any desire to make amends, but won't close off the doorway.
I also don't want to put undue pressure on other folks who are peripherally involved and entitled to make their own judgments about things.
So from here on out, I'll keep the public conversation on the logical level. The old posts still exist, they're just put away where they won't cause harm. I don't mind in the least making someone who did something wrong squirm and feel uncomfortable, and I'm not at all ashamed of my stance on the matter. But I *do* mind making another innocent party or parties feel uncomfortable.
So, to reiterate, this time in a less emotive manner:
1. Plagiarism is wrong.
1b. "Textual poaching", in the Jenkins sense, is not the equivalent of plagiarism, and to claim that by copying someone else's works in fandom you are by default not plagiarising is wrong.
2. Selling your personal fan fiction is wrong -- especially when doing so might endanger other folks' work.
3. Fan fiction is not by default equal to plagiarism. In many instances, fan fiction is not even a derivative work, but a transformative one.
4. Authors should *not* encourage uncredited copying of their texts into another person's story.
5. Saying that someone "inspired" your work does not constitute a credit for having taken whole segments (be they sentences, paragraphs or scenes)from someone else's work.
5. Credits should always be *specific* -- if you've taken paragraphs, whole scenes, or even just vague plotlines from another source, you should SAY SO and specifically.
6. Permission to copy should be obtained *prior* to publication, not after you get caught copying.
7. All of the above applies to published, real-life, paid authors' work as well as to fan fiction.
8. It's harmful to the notion that fan fiction is a legitimate creative endeavor to take text from someone else and reuse it.
9. Both online and offline fandom are insistent on proper credit and disclaimers being used.
