Abstract
Cyberspace offers up numerous possibilities for entertainment and leisure, and can be a rich source for information. Unfortunately, it can also be a dangerous place for the unwary or ill-informed. In this chapter, we discuss some of the legal and ethical issues that can arise in the interface between cyberspaces and real places for virtual tourists. We mention the difficulties posed by variations in laws in the physical world, and how these make for problems in the virtual world. We discuss how it is possible to create systems that embed adherence to laws and provide support for ethics in order to avoid harm to the unwary or ill-informed. We show how we have applied such principles in a machine ethics system for online gambling.
