I once fell victim to a similar disaster — CCing a group of recipients on an invitation instead of BCCing everyone. I received no less than 10 angry emails from contacts upset that their personal addresses were shared with a large group. I've also been on the receiving end of such a gaffe, but clearly never on this scale. Just another one to add to the list of top Internet mistakes of all time, I guess! Has something like this ever happened to you?
