Facebook said Wednesday it will limit the circulation of viral posts that are spreading a hoax story about men in white vans luring women into sex trafficking and selling their body parts.

The effort by the social media giant comes after Baltimore mayor Jack Young warned residents of men in white vans — even though the threat is a hoax.

“We’re getting reports of somebody in a white van trying to snatch up young girls for human trafficking and for selling body parts,” Young told WBAL TV last week.

“It’s all over Facebook,” he added.

In Detroit, a handyman told a local television station he’s been repeatedly harassed since the posts started going viral because he drives a white work van.

“A lot of people have been following me, trying to pull me over, trying to look inside the van and stuff,” Marcel Jackson told WDIV.

“It’s not me. It’s not me with the sex trafficking,” he added.

In a statement on Wednesday, a Facebook spokesperson said the company determined the posts were fake.

“Posts with this claim have been rated as false by third-party fact-checkers and we’re dramatically reducing their distribution,” the spokesperson said.

“People who see these false posts on Facebook, try to share them, or have already shared them will see warnings alerting them that they’re false,” he added.
