WASHINGTON POST -- July 31 -- The combination of young users and a culture that encourages sharing personal details presents opportunities for increasingly sophisticated methods to lure information. Last month, the FBI warned MySpace users of a phony bulletin post urging people to click on a link to "check out old school pictures." A virus seeking financial information recently invaded Orkut. A dozen sites that spoof the MySpace log-in page have been discovered. Scammers can look at profiles and better hone their attack.
Mark Brooks: It's best not to enter personally identifying information on any personals sites. No address, telephone numbers, license plate numbers... Social networks are designed not to be anonymous, so first names are ok. I recommend not entering your last name and age.
