Reverse psychology marketing?

Danny Sullivan blogs: Zeitgeist ’05: The Google Partner Forum is happening on Oct. 25-27, the first “customer innovation conference” Google says it has ever held. About 400 people are on the invite only list. …Speakers on the agenda range from the top three Google Guys, Larry Page, Sergey Brin and Eric Schmdit to IAC’s Barry Diller to MSN’s Yusuf Mehdi to Yahoo’s Terry Semel to Microsoft blogger Robert Scoble. The traditional press is well in attendance, with James Fallows of the Atlantic Monthly, New Yorker staff writer Malcolm Gladwell, the chairman and publisher of the New York Times Arthur Sulzberger and others. Excellent, can’t wait to hear what comes out. Wait a minute! The FAQ says:
All speeches and discussions at Zeitgeist are off the record. To ensure that our presenters and attendees can speak openly, no press coverage or blogging is permitted.
This will be good, to see if you can keep open discussions among 400 people, some of them bloggers, many of them press, somehow off the record.

Is this reverse psychology or reverse marketing? Or is there an old established term for this process in the industry? An interesting scenario to say the least. Not my field, marketing, but it fascinates me.
