Here's a question I've been meaning to post here since a conversation I had with Dan Hunter at State of Play last year:
Is there any subject matter that can appear in a virtual world which should always be banned by real-world authorities?
There are several caveats that we can make, but I'm only going to supply one for the moment: the virtual world is assumed to have effective methods for keeping out children. Thus, you might want to argue that full-frontal nudity (say) should always be banned, but if you did then you couldn't use "because children might see it" as your reason.
