Officials speculated that up to 40,000 illegal sex workers, mainly from Eastern European countries, would enter Germany for the Football World Cup , held in Germany in the summer of 2006. Women and church groups were planning a " Red card to forced prostitution" campaign with the aim of alerting World Cup visitors to the existence of forced sex trafficking. They asked for support from the national football team and the national football organization but were initially rebuffed.  In March 2006 the president of the German football federation turned around and agreed to support a campaign named "Final Whistle – Stop Forced Prostitution".  The Parliamentary Assembly of the Council of Europe (PACE), the Nordic Council and Amnesty International also expressed concern over an increase in the trafficking of women and forced sex trafficking up to and during the World Cup.    
A sex buyer in a research study explained that the woman in prostitution is “ just a biological object…that charges for services” Sex buyers define women as things. He tells us that the woman in prostitution is not human. But for some dissatisfied sex buyers, women in prostitution are not sufficiently compliant or object-like. David Levy says that what he likes about robots as opposed to prostituting women is “anonymity, brevity and the lack of emotional involvement.” Teaching men to have sex with robots makes empathy unnecessary. Research shows that sex buyers already have less empathy than non-sex- buyers . Sounds like they need more not less empathy. These I-like-rape-robots are what sex buyers want: a compliant thing that can be penetrated in any orifice and smile. See Sex Robot Matters: Slavery the Prostituted, and the Rights of Machines . As robot ethicist Kathleen Richardson has noted, “ Philosophies which advocate the breakdown of distinctions between persons and things are revised versions of arguments for slavery”.
