SEX offenders and people suspected of terrorist activity can now be reported to Facebook in in a major upgrade of user safety features by the global social networking company.With 400 million users worldwide, Facebook has been criticised for being too slow to respond to complaints of online bullying and sexual predators.In response the website has launched a safety centre, an internal site which gives advice to users about cyber bullying, with a designated area for teens on how to report offensive or inappropriate material, as well as information for parents.The site also includes advice for teachers on how to create professional environments to interact with students and deal with cyber bullying.Users can now report profiles belonging to registered sex offenders, or those offering support for terrorist activity.”If you find material that promotes terrorist behaviour or that raises funds for a terrorist organisation, Facebook strongly encourages you to report this here,” it says.The company unveiled its safety centre a day after meeting child advocacy officials in Britain, who had been pushing for stronger safety features for some time, following the kidnapping and murder there of a teenager by a man she encountered on the website.In Australia, numerous tribute sites for teenagers who have died in car accidents have been vandalised with offensive material. An example was a tribute page set up for eight-year-old Bundaberg schoolgirl Trinity Bates, who was abducted from her home and murdered.Similarly, Elliot Fletcher – the 12-year-old schoolboy who was allegedly stabbed and killed by another student – had his tribute page vandalised.In February, 20 students from Springwood State High School in Brisbane were suspended for setting up a Facebook group that bullied staff. And in the US, a 19-year-old has been sentenced to 15 years in prison after being found guilty of using Facebook to blackmail his classmates into having sex.The site is the first major initiative between Facebook and its global safety advisory board, which was established in December.”There’s no single answer to making the internet or Facebook safer,” said Elliot Schrage, vice-president of global communications and public policy at Facebook. ”You’ll see even more powerful – and simpler – safety innovations coming from Facebook.”-with AP
