But...

it's still not going to protect from new offenders that have never been caught.

MySpace tool to help block sex offenders

'NEW YORK (AP) - MySpace, the popular online hangout that has drawn complaints about sexual predators and other dangers to teens, said Tuesday it will develop technologies to help block convicted sex offenders.

MySpace is partnering with Sentinel Tech Holding Corp. to build a database containing names, physical descriptions and other identifiable details on sex offenders in the United States. The News Corp. site, however, stopped short of adopting Sentinel's technology for verifying the ages and identities of its users.

The database, to be called Sentinel Safe, "will allow us to aggregate all publicly available sex offender databases into a real-time searchable form, making it easy to cross-reference and remove known registered sex offenders from the MySpace community," Hemanshu Nigam, MySpace's chief security officer, said in a statement.'
