I don't really have any opinion on the "outing".
My first impression was that Brian posted the link because of the sketchy way the item was listed. High end card, one day auction, seller doesn't quite know what he has, or quite where he got it. Legitimate listing or not, it was one red flag after another.
I was really expecting a debate on the validity of the auction itself, not a three page argument revolving around who deserves to see the auction, and who doesn't.
