For a while now, the main sub I moderate had had issues with downvote bots / downvote scripts. Recently, the issues have gotten much worse. Now, no matter who posts a thread or makes a comment, within a minute it gets downvoted at least 2 times. I know this isn't just me as multiple users over the past few weeks have noticed and commented as such. It's honestly affecting sub morale.

There's GOT to be a way that reddit admins can run a script or something that doesn't allow / bans accounts that have a drastic upvote to downvote ratio. Of course, mods can't see who downvotes so we can't take action.

Is there anything I'm missing here?
