Nothing really goes to far, in my opinion. It's the readers opinion of what goes too far.

As long as there are codes and a brief synopsis of the story, the reader can choose to read it or not.

I read the violent stories, the snuff stories and all of the others in between.
Some I like and some I don't, they are stories and only that. They are meant to be read and enjoyed.

Write what you like and what you enjoy, there will always be a reader who shares your tastes.
