It's still baffling to me that so many subreddits have rules against downvotes and use CSS hacks to hide the downvote buttons (that alternate clients or using the preference to disable custom CSS easily circumvents) and that Reddit just hasn't added that as core functionality for moderators to enable on a subreddit. The only thing I can think of is that if they make it an option all subreddits will ban the downvote and for whatever reason admin must be really invested in ensuring people are able to downvote. One of the clever things I noticed about HN is that you cannot downvote replies to your own comments. It's an interesting tweak. On top of that the very recent rollout of changes to how blocking works are really wrecking havoc on debate subreddits where jerks are now using blocks to "win" debates.
