The internet is the number one mass medium. It combines traditional forms of broadcasting, film, and television, as well as classic printed materials. All the potential violations of personality rights that have already occurred and are known in these media can also be found on the internet, heightened by its own specific dangers. The rapid technical dissemination of information to an unmanageable user base leads to a accumulation of risks regarding violations of personality rights. As with no other medium, the benefits and risks of misuse are thus closely intertwined. Under the guise of anonymity, legally protected interests of third parties are compromised on platforms and portals, in forums and guestbooks of websites. Due to the global circulation of information and data, the number of personality rights violations increases both qualitatively and quantitatively. Therefore, the protection of personality rights is more significant now than ever. This book provides an overview of personality protection on the internet. It specifically examines which concrete types of violations appear possible, which legal protection instruments are available, and in what conflicting relationships these instruments stand with the rights of third parties. In doing so, the applicability and suitability of traditional civil law remedies in the online context are particularly scrutinized.
