I can see where you're coming from, and I sort of agree - although I would have loved to see the banned pics and judge myself. Alas, it is impossible.
The fact is, it works both ways - you can't prove a picture has a background story, but you can't prove it hasn't, either. Myself, I seldom do explicit pictures, often preferring innuendo for the very reason that it leads the viewer to imagine something more behind it, rather than just the utter porn... But it might be that sometimes a more brutally graphic scene is necessary to the story I wanted to tell through my drawing. So there we are, nack to the beginning.
Argh. I am not giving any explanation XD I suppose I should go get some sleep...
