This chapter examines the law on virtual crimes, including those covering Internet pornography, photographs and pseudo-photographs, and multimedia products. It discusses the difficulty of applying localised concepts of obscenity—which are dictated by cultural, religious, and societal values—in the global environment of the Internet. It also considers the issue of cyber bullying and harassment. It is shown that nation states have difficulty enforcing their own policies regarding what is or is not acceptable. However, matters assume a different perspective when there is a commonality of approach between the jurisdiction where material is hosted and where it is accessed. In this, the Council of Europe Convention on Cybercrime is a significant, albeit limited, development.
