We all post photos of our kids on our social media sites, but a woman in Phoenix found out that you can't trust anyone, not even your longtime friends, after one of her friends copied pictures of her daughter from her Facebook page and posted them on a Russian child porn site.

Ashley Williams said she trusted Christopher Madill and even said he was "one of my closest friends", that is until she got a call from Homeland Security in January. They told her that Madill had copied 83 pictures of her daughter from Williams' Facebook page and posted them to a Russian child porn site where he said he was her father and he molested her every single day. He also traded photos of Williams' daughter with other men who claimed to be fathers who molested their children.

Madill has been charged with five counts of sexual exploitation of a minor and is in jail on a $100,000 bond.

This is a really disturbing story, but it goes to show you that no one should ever be considered 'safe' where our children are concerned.
