Question: I have been looking for a writing software, but while I have seen a number of mentions about how this or that program helps you keep track of characters, I haven't seen any mentions of ones that are good at helping you keep track of information.

I am writing a Man vs. Nature story. There are only a few characters other than the protagonist, and they don't take much time on stage. What I need to keep track of is **data** - what food is available, how much of certain limited resources he has used, tracking his travel, that sort of thing. Are there any writing programs that would help with this?

If there are no writing programs that would do this, are there any other (non-writing) programs that could help me track this kind of information? Or even any techniques that would work well? I'm almost at the tearing-my-hair stage on this.

Answer: 
I have self-published several erotica titles under a pen name through KDP, and I've participated in a number of discussions about this in a writer's forum that I frequent. What we have seen over time is that there are certain topics that Amazon considers taboo, and those are pretty certain to get you banned. These topics include bestiality, incest, and non-consensual sex of pretty much any kind. There may be some writers who have managed to sneak in a book that might cross those lines, but these seem to be the main red flags.

As far as the graphic nature of your content, Amazon doesn't seem to be too restrictive unless it happens to cross into one of those forbidden territories. They don't have the resources to read and analyze every title submitted to them, so it would be hard for them to screen every erotic title that comes their way. The main thing they focus on initially will be your description, so make sure that you aren't too graphic there and that your description isn't offensive. 

Something even more critical than the content, however, is the cover of your book. If it depicts anything blatantly sexual or shows too much flesh, then it could get your book blocked or, even worse, labeled as an "Adult" title. If your book falls into that category, then it will usually be blocked from pretty much all search results and will find it harder to make any recommended lists.
Here’s the thing: KDP is quite different from books on Amazon in general. Those are Kindle Direct Publishing rules, but, say, books published by a publishing company that was added on Amazon by default would refer to a different rule book. Hope this helps!
