Sorry if it’s a dumb question. I’m not even knocking or shaming, I just think they’re really funny and want to see more if you know of them. Not accounts that downvote, accounts that ONLY downvote. Rare ones. Like weapons-grade haters.
I’d collect them in my user tags. And like, just observe what they respond to.
My instance has downvoting disabled and (I think) also does not federate downvotes. So 0/default is as low a comment score as I’ll ever see!
