Sex trafficking
Sex trafficking is human trafficking for the purpose of sexual exploitation, including sexual slavery. A victim is forced, in one of a variety of ways, into a situation of dependency on their trafficker(s) and then used by said trafficker(s) to give sexual services to customers. There are three types of activities defined as sex trafficking crimes: acquisition, transportation and exploitation; this includes child sex tourism (CST), domestic minor sex trafficking (DMST) or other kinds of commercial sexual exploitation of children, and prostitution. Sex trafficking is one of the biggest criminal businesses and it has been described as "the fastest growing criminal industry in the world."
Sex workers' rights
Opponents of the sex workers' rights movement, such as Melissa Farley and Janice Raymond, argue that prostitution should be abolished because legalization can increase incidences of human trafficking. The "New UN Trafficking Protocol" by Raymond argues that many victims are trafficked to countries in which sex work is legalized or decriminalized, and because they are trafficked under the guise of migrants they are not protected. Raymond also argues that it is impossible to separate the exploitation experienced by local prostitutes from the exploitative experiences of trafficked prostitutes, as they are very similar. Thus, to end sex slavery, the report declares that everyone involved in sex work needs to be criminalized so that the industry can be abolished. Similarly, Farley argues that engagement in voluntary sex work is a decision made by women in the absence of alternative choices, and that it therefore cannot accurately be described as a voluntary and freely made choice.
