Insex: Insex was one of the biggest BDSM pornographic websites on the Internet and arguably the most extreme American pornographic production featuring female submissives.  It was also a leading innovator in both live video streaming, pioneering the concept before broadband Internet access existed, and in the depiction of BDSM practices on the Internet.  It existed from 1997 to 2005 and was run by "Intersec Interactive Inc.", a company owned by the website's creator, Brent Scott, former Carnegie Mellon professor, known as "pd".  Insex developed a cult following among BDSM enthusiasts due to its uncommonly severe and realistic depiction of sadomasochistic practices.  It was also known for its interactive "Live Feeds" which allowed members to make direct suggestions and requests.  In late 2006, Insex ended the production of original material, citing increased pressure from conservatives within the U.S. Justice Department. <ref name="BD/SM Internet Sites Under Attack">McMillan, Dennis.

Memory of Mankind: Several motivations underlie the project.  The primary ambition of MOM is to preserve an image of our era, created by numerous participants all over the planet.  MOM will also contain information which our society is obliged to forward to the future: e.g. description of nuclear waste repositories.  MOM collaborates with the NEA and SKB.  Although the most obvious ambition and often described in the media is the concern about preserving our knowledge, this is not the primary goal of MOM.  Serving as a time capsule MOM is both: in a time frame of millennia it is the story about us, and in a time frame of decades it is a backup.  In times where global warming, nuclear danger and biological warfare threaten the existence of civilization, saving the core knowledge and culture acquired over centuries is a backup measure.  In case of a collapse, the MOM project could help survivors to rebuild civilization.  Linked to this, an another reason is of political order: facing the lack of reactivity of authorities concerning global warming, the MOM project is a reminder of what can happen.  Roman and Greek civilizations whose histories have been reconstructed by the small percentage of texts and artifacts which survived until our days are examples that have inspired the MOM project.  Finally, it's a critic of our digital civilization : according to Kunze, maybe nothing of the 21st century will last in the future, since most of our interactions are now virtual.  The "accuracy versus bullshit" is one of the main themes of the MOM project, worried about loss of information, the project can only aim to save a fragment of the information produced until today, but this fragment has to be representative.
