1) I am not able to answer this question as I am no expert on extreme content (I stay no higher than 18+) You might find some answers here: "Content Rating Support" 

2) You will still have a link to copy and paste into emails, facebook, etc. It just would not be found via Writing.com searches

3) Yes two stories with the remaining items being what you want the rest to be. (As static items)

4) You can if you make ending each as a static item and on the main story you write something like: To read the dragon fell asleep click here. To read the dragon flew away click here. (It would be worded however you wanted due to whatever story you wrote)
