Kutcher is the co-founder of the organisation, Thorn: Digital Defenders of Children.

Speaking at the U.S. Senate Foreign Relations Committee hearing, Kutcher said he is often told by others to “stick to his day job”.

“This is about the time, when I start talking about politics, that the internet trolls tell me to stick to my day job, so I’d like to talk about my day job,” he said.

“My day job is the chairman and co-founder of Thorn. We build software to fight human trafficking and the sexual exploitation of children. That’s our core mission … We [are] their last line of defense … That’s my day job. And I’m sticking to it.”

According to the organisation’s website,a large part of their work “comes from informed research collected in the field, which helps our team, along with our many partners, remain on the cutting edge of technology. Sometimes we conduct primary research and bring new information to field, such as establishing that 63% of child sex trafficking victims (we surveyed) were advertised online, and 42% of sextortion victims met perpetrators online.”

Kutcher revealed that a video that was shared of a seven year-old girl being raped “haunted” him and made him want to help the Department of Homeland Security locate this little girl to try to and save her.

“It haunted me. Because every night, I had to go to sleep every night and think about that little girl who was still being abused, and the fact that if I built the right thing, we could save her. So that’s what what we did. And now, if I got that phone call, the answer would be ‘yes.’”

“Technology can be used to enable slavery, but it can also be used to disable slavery,” he added.
