You don't have to be nice about it. If my partner is a kennedy, I can dump the game and nobody cusses me, because I'm completely anonymous.
What I hate about it is someone who is being stupid and bids a blind nil when there's no reason to do so, because you can't effectively cuss an anonymous person.
