Kutcher says, "tweet @craignewmark with solutions"

WENN.Com-The Killers star set up The Demi and Ashton (DNA) Foundation with his wife Demi Moore to raise awareness about the harrowing subject and to provide support to survivors of abuse.

Kutcher is concerned about how some sex traffickers have been using Craigslist.com to solicit business online - and he's helping the website's founder, Craig Newmark, come up with ways to weed out the offenders and ban them from using the listings service for good.

In a post on his Twitter page on Wednesday (04Aug10), he writes to fans, "Do U have ideas how 2 help Craigslist fight human trafficking? pls (please) send all responses to @craignewmark."

Kutcher has suggested naming and shaming those caught "browsing adult services", by asking them to enter their credit card information before viewing the search results, while he has also proposed Newmark donates money from the illegal posts to fund new technology preventing such adverts appearing on the site.

He states, "If u dedicate ur profits from this illicit trade toward a tech solution 2 shut it down we could solve this issue."

But he is grateful for Newmark's support for his foundation's campaign to bring an end to human trafficking.

He adds, "Lastly @craignewmark it's nice to see u being an activist for this cause. I hope these ideas help."

And Kutcher has invited Newman to attend his organisation's next discussion about the cause: "@craignewmark love to see u at the next dnafoundation trafficking tech task force meeting."
