"The Jensen Project" uses Sky Writing to expose sex traffickers' social media tactics.

You know whenever you see skywriting that you look up and patiently wait until you can read the full message? They always grab attention, as it might be something sweet like "ELIZA WILL U MARRY ME?" or funny, like "HOW DO I GET DOWN?" - either one would have you nudging a pal and pointing up to share what you've just read.

No Fixed Address has tapped into this phenomenon by showing us sex traffickers' creepy messages in the sky. "HOW OLD ARE U?" is pretty creepy when you think about it, and worse is "NO ONE HAS TO KNOW".

They did this in the skies above Dallas, one of the top 10 cities for sex trafficking in the country, to get the attention of young people who may be the target of such trafficking. After seeing this in the sky, and discussing it with friends, that "HOW OLD ARE U?" in their DMs might not seem so innocent anymore.

“Sex trafficking is happening in cities across the country and the more it happens, the closer to home it gets,” said Janet Jensen, founder and executive director of The Jensen Project. “To stop this epidemic, we need to be able to spot it.”

“While some may not understand the severity of this issue, we’re providing them a glimpse of what it might look and how close it can be by writing real and common trafficker messages above neighborhoods in one of America’s largest trafficking hubs,” said Alexis Bronstorph, the chief creative officer at No Fixed Address.

The scariest nad possibly all too familiar line for some written in the sky was: "Leave And I’ll Find You"
