Story points to potential social networking dangers:

I originally posted about Robert Harris and Richard Johnson here. They were half of a four man crew that were running a prostitution ring on craigslist  in Millersville, Maryland in order to buy ecstasy and gold teeth. Which I think in this context are pronounced 'teef'.

That crew was also prostituting out underage girls from Ohio.

Harris and Johnson have both pleaded guilty.

According to authorities Harris also tried to tamper with witnesses from behind bars.

The other half of the crew, Craig Allen Corey and Jacob Tyler, are still awaiting trial.

Harris and Johnson are still facing life behind bars.

However the fact that they got around craigslist's supposed screening but they used MySpace and YouTube as well. But for that part of the story you'll have to go here.
