>In the long run, rational players should always refuse to such offers. If scammers would know that everyone always refuses, they'll quickly get into a loss and stop doing that. The problem is that I'm not sure how people would react in such situations - why not take the 30%? People have a very strong fairness instinct, and will probably refuse such blackmail. There's a famous experiment where some amount of money is given to one person, and he decides how to split it with a partner (50-50, 100-0, etc.). The partner decides whether to accept the deal or refuse it, in which case the money is lost. If I remember correctly most people refused offers under 20%, and that's without the anger that someone trying to blackmail you would cause.
