A bill co-sponsored by South Dakota Representative Kristi Noem to combat online sex trafficking was signed into law on Wednesday.

The legislation will give law enforcement and victims more tools to fight sex trafficking by allowing states and victims to go after websites that facilitate trafficking, imposing stiff penalties on those websites and taking away immunity from websites that profit from trafficking.

Noem said this was a step in the right direction for justice and protection for trafficking victims.

"We still have more work to do to really, truly get this opportunity to protect our kids fully realized, but already we are seeing huge changes in the mechanism that abuse our children are utilizing," she said.

Since the legislation was passed by Congress, Craigslist and Reddit have shut down personal ads on their websites, and federal authorities have seized control of and indicted executives at the website "Backpage."
