Actually, the idea of requiring financial donations shouldn't be dismissed out of hand. A system of micropayments could conceivably function as a deterrent to trolls and vandals. Let's suppose, just hypothetically, that Wikipedia had a system whereby people who engage in trolling or make lots of controversial edits could be required to pay the Wikimedia Foundation 5 cents for every edit they make. (Maybe there could even be a cash *incentive* so that people who have earned a reputation for good editing would *earn* small amounts of money for their edits.)
