Anshe Chung Studios cracks down on griefing photos
  ... an indulgence in truly asinine, arrogant bullshit.

As "Anshe Chung", the Graefs are an SL celebrity aka "public personality", and the photos and video were taken at a PUBLIC INTERVIEW with CNET NEWS. No one chased AC to get the photos -- by appearing to be interviewed, he/she/it/they made the "artwork and textures of the Anshe Chung avatar" public by doing so in a media-oriented setting. Furthermore, they may have IP rights to the "Anshe Chung" persona, but the avatar was created using SL's servers (and presented in the media event using other people's work product: skin, shape, hair, eyes, clothing, jewelry, and the textures for all those items). The avatar AC and his/her/its/their activities take place using LL-owned servers, and NEITHER THE AVATAR "ANSHE CHUNG" NOR HIS/HER/ITS/THEIR BUSINESS ACTIVITIES EXIST OUTSIDE THOSE SERVERS. The only use for an SL avatar is INSIDE SL; the presumption is that the avatar will be used in-world to make contact with other subscribers. Ergo, any subscriber who appears in the public areas of SL in any avatar form has no presumption of control over screenshots of their avatar (since there is, to my knowledge, no effective contract law in SL, and RL contract law regarding use of one's name and image may not apply to what is basically a cartoon image created solely for use in a computer-networked environment which is WHOLLY OWNED by the company running that environment), and no control over such things as chat logs, logged IM conversations, machinima videos created in-world, etc. When the avatar/subscriber is appearing on a publicized media "event" in which they agreed to participate, there is no presumption of privacy, no possible presumption of control, apart from the agreement to appear for the event.

In fact, by whining about their claim of copyright in this instance, the rich bitch and her bullyboy hubby both qualify as wienies in their own right -- so the entire incident could be described as one whiny wienie being overblessed by an onslaught of multiple wienies produced by other wienies (the latter being the childishly vindictive griefer/s).

The Graefs are only whining because the griefers ruined their pretty PR stunt, and this is their way of pulling the classic 10-yr-old tactic: (whine) "Well, you're not playing by MY RULES, so I'm taking my bat, my baseball, and my glove HOME. So there! (huff... pout... flounce offstage)

I'm surprised PROFESSIONAL JOURNALISTS, who are well aware of the legal limits of constraint that PUBLIC PERSONALITIES can place on use of their images and accounts of their behavior, are caving in to this childishly bitchy attempt at playing Gestapo.
