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?

You mean allowlist federation? Depends on who you’re federated with. If you’re federated with any larger server it’s still going to be an issue.
I added a site setting to reject federated votes that’ll be in the next release.
I think they meant disabling downvotes altogether.
Ah, yep that’d do it.

I split them out into 4 options: post, comment, upvote and downvotes
You could make the community local only, but that would very much limit its reach.
yeah i meant just killing downvotes by default
