The present study examines a range of moral issues associated with recent cyberstalking cases. Particular attention is centered on the Amy Boyer/ Liam Youens case of cyberstalking, which raises a host of considerations that we believe have a significant impact for ethical behavior on the Internet. Among the questions we consider are those having to do with personal privacy and the use of certain kinds of Internet search facilities to stalk individuals in cyberspace. Also considered are questions having to do (...) with legal liability and moral responsibility that Internet Service Providers have for stalking crimes that occur in their "space" on the Internet. Finally, we examine issues of moral responsibility for individual online users to determine which obligations, if any, they might have to inform persons who are targeted by cyberstalkers, when it is in their power to do so.
