Every digital space operates under its own "natural" laws. There is no certainty that the laws of any one space will hold true in any other. A MUD (Multi-User Dimension; a multi-player piece of interactive fiction where the users create the story), for example, may have specific laws regarding the behavior of players within the space (i.e., players may be allowed to physically or verbally attack each other), whereas identical behavior in a different space (verbal fighting in a chat room, for example) may have very different consequences.
