There doesn't seem to be an expressly specified code around voting, and I suspect that this might be a deliberate attempt to let the community decide out of unspoken consensus. When concern about the basis of a vote is expressed, it's often made clear that the grounds for up voting and down voting are not symmetrical. I can't decide if I think that they should be or if it doesn't matter. I'd really like to see a list of controversial posts (many votes in both direction) to determine whether they are mostly matters of agreement/disagreement or if there is usually some less personal ground (e.g. expressing a factually wrong but popularly held belief, differing opinions on what adds to the discussion or not etc.)
