I support opening up vote logs to moderators in their own communities. Voting records add useful context to the nature of the exchanges happening, eg. if two people are having a back and forth, but neither is downvoting the other, it contextualizes the disagreement as less hostile.
I don't think it's a good idea to give every new user the burden of using that information responsibly. A minority would use it to retaliate, stalk, and harass, and there would be too many of them to reasonably hold them accountable.
