Traffickers usually go for easy targets including people who have experienced or been exposed to other forms of violence. Some may include child abuse, maltreatment, interpersonal violence, sexual assault, and gang violence. Traffickers look for people disconnected from stable support networks: runaway/homeless youth, unsupervised minors, and people displaced during natural disasters. Some ways people get into human trafficking:
Recruiting: forceful targeting of defenselessness and grooming behaviors
Harboring: isolation, confinement, monitoring
Transporting: movement and arranging travel
Providing: given to another person
Obtaining: forcibly taking, or exchanging something for the ability to control
Soliciting: offering something of value
Patronizing: receiving something of value
