Facebook's shocking trend of rating teen's sexual prowess sparks outrage

In a disturbing new Facebook trend in Australia, teenage lovers are being rated on their sexual performance on a scale of 10 before the ratings are published for public viewing.

Anti-bullying and child protection experts have raised worries about the sites, which are being run by anonymous administrators, and have called on Facebook to shut them down.

Several hundred users, mostly secondary school students, have signed up on these sites.

Child Wise chief executive Bernadette McMenamin said she was horrified by the phenomenon.

"I am continually shocked by the way young people are being sexually exploited on the internet," News.com.au quoted McMenamin as saying.

"It is an indication of just how sexualised our society has become when it comes to young people," she added.
