Is it time to disable guest comments and their ability to upvote/downvote? I’ve noticed over the last several weeks that most of the trolling/hate speak/etc. comes from guest posts. I’ve also noticed that when I’m not logged in for whatever reason, I’m still able to vote on posts — then I log in again, and I can vote a second time. At the very least, if a commenter doesn’t want to go through the minimal effort to register, they probably shouldn’t be able to affect the ratings of other people’s comments (and thus, points).
