"Porn": the oh-my-god evil word. Anybody shiverering and shaking? Well, not me. Porn, so what? Porn is an form of artistic expression among others. From Pompeji to Picasso to modern time gonzo movies clips. There is good porn, there is bad porn, which is which is in the eye of the beholder. What are you afraid of? People do porn and nothing else? I don't think so. I don't see a reason to warn of a danger, because I don't see one. German phrase: "Du malst den Teufel an die Wand". "you paint the devil on the wall". You see a danger, where is no danger at all.

You might think, the word "porn" is powerful enough to let people think it is a threat, at least for me, it is not. Is it dirty? If it's done the right way, yes.
