The lawyers who filed the latest lawsuits said the plaintiffs include a 15-year-old girl from Texas who was lured to a meeting, drugged and assaulted in 2006 by an adult MySpace user, who is currently serving a 10-year sentence in Texas after pleading guilty to sexual assault.
The others are a 15-year-old girl from Pennsylvania, a 14-year-old from New York and two South Carolina sisters, ages 14 and 15.
Last June, the mother of a 14-year-old who says she was sexually assaulted by a 19-year-old user sued MySpace and News Corp., seeking $30 million in damages.
That lawsuit, filed in a Texas state court, claims the 19-year-old lied about being a senior in high school to gain her trust and phone number.
New safety tools
Critics including parents, school officials and police have been increasingly warning of online predators at sites like MySpace, where youth-oriented visitors are encouraged to expand their circles of friends using free messaging tools and personal profile pages.
MySpace has responded with added educational efforts and partnerships with law enforcement.
The company has also placed restrictions on how adults may contact younger users on MySpace, while developing technologies and tools.
