Should we side with @themarkymark and stop people from upvoting during the last 12 hours before payout? Why not?

Yeah, why not? It will help us get rid of a lot of spam with less work. Which will give everyone more time to think about other problems/solutions. This sounds like an "easy fix", at least for now. I'm not the one actually doing the downvoting but if this can help those that fight the abuse, then it should be implemented again... I think.
