Does Lemmy have any moderation tools for dealing with users that always vote down posts because they disagree with a community?
For want of a hypothetical example, say someone created a community dedicated to pineapple on pizza. What’s to stop people who strongly disagree with pineapple on pizza to subscribing, and voting down every post?

Ah, yep that’d do it.
It is only a partial solution imo, I had downvoted disabled on vegan theory club but people would still downvote the posts and it would federate to all the other servers except mine and I couldn’t moderate it. We were targeted by shut ins and the threads looked bad on other instances and I couldn’t see or ban the users lol. I guess rejecting federated votes would help but then there would be no federated upvotes either.
You could make the community local only, but that would very much limit its reach.
I split them out into 4 options: post, comment, upvote and downvotes
yeah i meant just killing downvotes by default
