I read (not all but) many questions about automatic bounty awarding. e.g.: How does the bounty system work? and Automatic award of bounty.
And in How to willingly not award a bounty? I found:
... after all. If you think the upvotes are fraudulent, you should report the post to the mods. ...
But how?
Background: I asked this question about Ruby on Rails and Haml. After 'bountying' it, I got an answer that does not even fit to my question. So I voted it down, but for some reason it got the additional three votes to qualify for the automatic award system. And the answer would not be qualified for upvoting (it's confusing, and no explanation) even it would fit to my question.
And it's the copy of Ruby on Rails Ajax call runs controller code, returns success, but not rendering view.
