North Carolina Attorney General Roy Cooper said he plans to keep pushing social networking sites to "clean up their act" after MySpace revealed Tuesday that 90,000 sexual predators are members.

"This just confirms what we in law enforcement already know -- that child predators are using social networking sites to prey on kids and that we must keep pushing these sites to clean up their act," Cooper said. "Technology should play a role in keeping children safe on the Internet, and social networking sites must put better safety tools in place to keep these predators away from our kids."

The 90,000 total includes 40,000 more offenders than the company previously acknowledged it had found on MySpace.

The news from MySpace casts doubt on parts of a recent report by a Task Force charged with finding and developing technologies to make social networks safer. Cooper, Blumenthal and other attorneys general criticized the report for using outdated research that predates the emergence of social networking sites and for minimizing law enforcement reports that child predators are using these sites to find their victims.

For more than three years, North Carolina Attorney General Roy Cooper and Connecticut Attorney General Richard Blumenthal have led a group of Attorneys General who are pushing to make social networks safer, winning landmark national agreements with MySpace and Facebook in 2008.
