And if others were to make even 20 dollars on a post, that is motivating as well. Very motivating. So instead of people piling on and padding his payout, they should be limiting that and voting for their fellow 2 and 5 dollar payout users.
If out of 15k , 5k went to dollarvigilante and 10k was spread to 500 users, that would have done much more good overall for the system. Dolla' gets more than enough motivation to keep doing what he's doing, and a lot of the base users get some reward for their time. Of course this is only if their content is upvote worthy. Not at all suggesting that people should get rewarded for crap.
