Sponsors will go on my "Permanent Boycott" list.
"Permanent Boycott" means the corporation has engaged in activity so egregious they will never see a dime of my money again. (Needless to say, it's applied rather sparingly.) Once on my "Permanent Boycott" list it's rather difficult to get off because (to keep it manageable) I don't bother remembering how they got on, just that they're on it. General Mills was the first to earn a spot, 6+ years ago (I think); we haven't bought anything with a General Mills brand since.
