Should we reduce rep bonus for upvotes on posts with a negative score?
The issue of "Pity-Upvotes" has received a bit of attention, most notibly here: Is there an actual "pity" or "sympathy" upvote problem?. It seems that I encounter this on a pretty regular basis... truly terrible questions (one sentence, "do my homework", etc) or answers (obviously just a comment, wrong answers, etc) which receive three or four down-votes and suddenly an up-vote appears which I can only presume is a pity-vote ("It wasn't soooo terrible...maybe I'll just boost them back to -3").
I don't necessarily have an issue with the thought behind this, and sometimes merely mediocre posting ends up a -6 or more, but because of the skewed weight of up and down-votes the targeted post will often end up in the black despite being a pretty poor effort.
A proposal for remedying this issue: weight the reputation value of up-votes as only +2 (on par with down-vote) when the aggregate score is less than -2. This preserves the value of up-votes when there is a legitimate difference of opinion on the quality of the question/answer (a good posting will sometimes have a less than zero score, but almost never more than -2) and gives users the ability to vote "this question/answer isn't as terrible as the score would suggest" without rewarding lousy posts. Does this seem like a reasonable proposition?
