Essentially, child sex trafficking is the buying and selling of any person under the age of 18 for the purpose of sexual exploitation. That encompasses a child being recruited, enticed, harbored, transported, provided, obtained, patronized, solicited, or maintained to perform a commercial sex act. A child can never be responsible for, or complicit in, their own abuse. The U.S. Department of Justice and United Nations, among other authorities, define child sex trafficking as modern slavery.
