Recent concerns surrounding MySpace have resulted in Fox Interactive Media's hiring of former Justice Department prosecutor Hemanshu (Hemu) Nigam as chief security officer in an effort to ease parents' concerns, reports CNET. Nigam, who as a prosecutor specialized in child-exploitation cases, will handle all education, safety, privacy and law-enforcement programs for MySpace and other Fox online properties.

MySpace has also hired more employees to handle security and customer care; about 100 employees, one-third of the workforce, seek out inappropriate content or underage members.

"Lots and lots of parents want their kids' profiles down," said Parry Aftab, executive director of WiredSafety.org, a nonprofit that provides safety and health information. It has worked with MySpace and other social networks to design safety guidelines.

MySpace has also partnered with The National Center for Missing & Exploited Children (NCMEC) and the Advertising Council to launch a print, television and interactive ad campaign targeting online teens.
