Banning trolls would be doable - they’d have patterns where they target specific users across many different communities. If the same user downvotes everything I’ve ever said, from controversial political takes to pictures of food to posts about gardening, that’s probably a malicious user.
But “brigading” doesn’t mean anything and I don’t respect the concept. You can’t ban it because you can’t define it in a way that doesn’t include normal usage of the site.
How long until it gets abused, and trolls start brigading though instances that hide their votes?
Nothing stops defederation, though.
That creates an incentive for trolls to create accounts at the popular instances using this mechanism in order to destroy their reputation.
But they can just be banned from those instances?
How would that work? How would an admin separate downvotes from brigaders and legitimate users who happen to downvote a comment?
