My blackmailposts have generated some interesting discussion, so I'm just creating this one so that people can post examples of behaviours that they think are either clearly blackmail, or clearly not blackmail, or something in between.
Blackmail. A wouldn't make the threat if A believed that B ignored such threats, and A would have no motive to paint the car green if B were a rock. Pricing of green makes no difference so long as the price is not negative.
Defining what a rock is is akin to defining what the status quo/disagreement point is. What if B were an automated rock that responded to "I'll paint it green" with "please don't, I'll offer £10", what would your feelings be then?
In this example that seems a little gratuitous, but I'm sure we can construct other examples where it's much more natural...

I assume you meant to say that (price of green - price of black) is not negative. If the price of green is £0.5 then it is not blackmail.
