Colleges and universities must inform students about the particular dangers they face online. But if schools actively monitor their students’ online activities and students are aware of this policy, they may have a duty of care that includes preventing any illegal acts committed as a result of information posted online.
Thus, schools should inform their students about the potential dangers of using social networking Web sites, but should also be careful not to become liable if the students engage in illegal behavior. —Sheldon Steinbach and Lynn Deavers —The Brave New World of MySpace and Facebook (Inside Higher Ed)
