Brigaders.
People with like 10 accounts that upvote themselves/downvote dissent.
Kbin votes are public so we can see brigades in action.
Apparently Lemmy votes are too but it’s not accessible in the native interface, only from Kbin. Maybe a third party client will implement it.
It’s super obvious when it happens to you, but it’s not obvious when you see it in the wild. It would be a great improvement to the site to just show the users who downvoted/upvoted.
I also noticed sometimes after getting into an argument it’s like they go through my profile and start downvoting everything. I feel like any vote that comes from someone’s profile (rather than in the wild) should be flagged as suspicious because it feels like they’re never genuine.
