More than a dozen students at a Minnesota high school were disciplined recently for party photos in a social site. They were suspended from sports and other extracurricular activities for allegedly posting photos in Facebook in which "they are either in the company of those consuming alcohol or holding alcohol themselves," KARE-TV reported. "The ACLU says there are concerns about schools mining through student profile pages but that what happened at Eden Prairie isn't a surprise." ACLU executive director Charles Samuelson told KARE that the students' rights weren't violated in this action because of the school's stated policy of zero tolerance for drug or alcohol consumption by students participating in sports or extra-curricular activities. If those students end up going to University of Minnesota-Duluth, social-networking-related policy goes a step further, KARE reports. UM-Duluth's athletic department "requires its student athletes to sign a statement saying they understand that if they choose to create a MySpace or Facebook profile, that profile is subject to review at any time, for any reason." The University of Minnesota is Facebook's second-largest network of users in the US, KARE adds.
