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."
