News Corp.'s social networking site, Myspace, will begin offering technology to identify and block convicted sex offenders from its networks, the company said on Tuesday.

The top online social network has large following of teens who are attracted to its music and personalization offerings. Adults preying on underage Internet users also use the site.

We are committed to keeping sex offenders off MySpace, the site's chief security officer, Hemanshu Nigam, said in a statement.

The new technology, called Sentinel Safe, will let MySpace search state and federal databases to seek out and delete MySpace profiles of registered sex offenders. It will be available in the next 30 days.

The company said the new service will be the first national database that brings together about 46 state sex offender registers.

Myspace had 56 million unique visitors in October, according to research firm comScore Networks. Similar sites, Facebook and Windows Live Spaces, gained 15 and 9 million visitors respectively.
