I think Elmer's case is a little different, seeing how EVERYONE that was at Fanfest got an invite.
Eh, at best the whole thing is a gray area and a matter of opinion. There's very little difference between saying "I attended Fanfest" and "I have an e-mail from SE in my personal inbox." In neither scenario had either yet agreed to the NDA.
Ontop of that there's a post floating around where someone tells how their machine handled the beta, so by your definition, they're guilty as well even though they only discussed their personal hardware.
It's not like anyone came on and said "holy crap, the end boss is a moogle that poops lightning and burps thunder and you beat him by attackng at a 30 degree angle from he left!!!" Edited, Jul 12th 2010 2:32pm by Sephrick
