It would seem that Rob would need to publicly post that it was wrong to reveal PM information between Rob and Rayzz. If Rob felt strongly about it, he could mark it as a Violation, go through the hoops, etc.
My understanding is that both have very strong convictions concerning their opinions about KRY's situation. I greatly respect both of their opinions.
The info that Rayzz quotes does not seem to show anything except for what might be considered an attack on Rayzz. At least to me. Of course, I am not privy to anything previously PM'ed between them so I do not know the complete story.
