Slavery is so illegal in the developed world that it's not even an issue. When people engage in human trafficking, the law enforcement apparatus puts the full brunt of its power into punishing the perpetrators. The government spends substantial sums of money preventing these sorts of abuses. The government wants to stop copyright infringement, but it doesn't want to spend any money doing it. So they implement regulations requiring corporations to do the policing and punishment of copyright infringement for them. The result is that Facebook, Google et al have sophisticated mechanisms to cheaply enforce copyright at scale, without human intervention in nearly all cases, and the mechanisms to enforce human trafficking violations is the legal office where a highly paid lawyer personally receives subpoenas and manually complies with them by personally escorting the FBI into the server room to verify the chain of custody. Dealing with countries where human trafficking is as illegal as j walking just isn't something Google has tools for. Highly automated ML mechanisms are fine for when the punishment is your content gets demonetized or taken down, but it's not fine when the punishment is twenty years in federal prison.
