Title.
There is no reason to downvote art on a site where blacklists exist. People just use it to express art they don't like, not art that is genuinely poor in artistic skill, political or any other valid reason for downvoting. The fact that something like gore artwork can still get downvoted today even if it's made well and despite everyone knowing about a blacklist now is a failure on e621's part. Get rid of downvoting on art.
