How about.....don't leave any [feedback] for them?
Not leaving positive feedback for others is a good way to minimize the total amount of positive feedback you receive.
Think of it this way: a certain percentage of users almost always leave positive feedback. Another certain percentage almost never leave positive feedback. There is probably not much you can do either way to influence either of those groups to change behavior.
But there is also another group that only leaves positive feedback in response to receiving positive feedback. Some are sellers that are convinced that buyers should leave feedback first; some are buyers convinced sellers should leave feedback first. Either way, if they do not receive positive feedback from the other party, no positive feedback will be left. When two of these users are involved in a transaction together, neither party receives positive feedback, since each is waiting for the other to blink first.
Aside from doing what you can to ensure a transaction goes as smoothly as possible, leaving positive feedback first is one of the few things you can do to influence someone to leave positive feedback for you.
