Some people urge Facebook to learn from MySpace and make its community network safer, according to an article in Business Week on October 8, Beijing time. Richard Wistocki was not a 14-year-old girl in the registration record. He is a detective aged 41 under Naperville Public Security Bureau Computer Crime Division. However, he pretended to be a girl named "Sierra" on Facebook's community network. When his real identity was discovered later, Wistocki said that Facebook did not work hard enough to protect minors from being hurt. For example, on Facebook, Sierra can make friends with people of any age and accept invitations to join some organizations. The virtual girl could participate in online activities organized by the organization, such as information sharing, picture transmission, etc., some of which are pornographic pictures posted by organization members.
