Culture of "not outing" auctions

[Snapolit1]

3 or 4 times in recent years I've purchased something at an auction (including Sotherbys) and someone has come to me after the fact and expressed reservations about the authenticity of the item or whether someone had done work to it. Each time I've wanted to say 'gee. . . . thanks, but would have been cool if someone had expressed that to me before I shelled out hard earned bucks for it." Of course none of them knew what was running through my mind. But all heeded the unwritten rule about not drawing attention to running auctions, lest you might accidentally crap on some friend or loyal board member who is trying to maximize how much he makes in a sale. No need to share the fruits of your labors with others kind of thinking,

Funny now reading all the posts about Mile High. Is this unwritten rule repealed or modified? What about the next time you see something on BST that doesn't look right? Do you say something or opt for caveat emptor and turn your head?
