Inara Pey has a tutorial on the use of media and privacy in Second Life. Quoting from her blog:
“While the media capabilities in the Viewer are very flexible, it is important to remember that they can also be used by others to capture information about yourself without your knowledge – and that this information can easily be transmitted to databases outside of Second Life and outside of Linden Lab’s control.”
