10 people want Mafia Wars to send out less messages about game developments.

I want Mafia Wars to stop putting inane messages like "Luke has travelled to Cuba", or "Luke has deposited $6m into the bank", as the more pointless messages the application publishes (against my wishes), then the higher my chances are of ****ing off my friends because they're fed up of seeing every little thing I do. It's annoying me as well, and I'll probably stop playing the game if I can't sort it out, so does anyone have any ideas as to how I can stop the useless notifications from being published all over my Facebook?
