has it stopped? I have set a bounty on a question at on SO. only 3 days remain. and today i find some one up-voted an answer that was answered before the bounty was set. if some one is just trying to up vote an answer to get it the bounty that defeats the purpose. I don't mind losing the bounty for advertising . But i don't want it awarded to some one who has not provided the answer. and if i had the reputation i would have down voted it...
Edit: what is the prevent some one for just messing around and upvoting any ridiculous answer in any bounty just to see that some one get the reward.
