ABSTRACT

Introduction The previous chapter focused on crimes which either caused damage to computers or computer networks or which resulted in pecuniary loss to individuals or organisations. In such cases, the loss can be measured in fi nancial terms. The discussion in this chapter will focus on another type of activity which has been made signifi cantly easier by the increase in size and capability of computer networks and which is damaging in a different way: the propagation and dissemination of criminal content.
