As if porn sites and pedophiles in chat rooms werent frustrating enough for parents whose children use the Internet, now online postings of amateur video featuring skin and violence are raising concerns.

The explosion in online video-sharing sites, where clips of any nature can be easily uploaded for the world to see, has become the latest challenge for parents trying to protect their children and for Web sites coping with obscene submittals.

Carol Kiesman, a mother and teacher in Houlton, Maine, enrolled her 14-year-old daughter in a cyberspace club called Zoeys Room, so the teen could chat away online with other girls in a gated community where all participants are screened.

Imagine then how Kiesman cringed when she saw her daughter, 10-year-old son and fourth-grade students recently encounter homemade videos online that included nudity and animal cruelty.

I dont like that innocent kids can click on stuff like that, Kiesman said What you view as entertainment as an adult shouldnt be entertainment for 13-year-olds.
