Honestly, not implementing anonymous voting probably helps with preventing brigading, too. Reddit worldnews (around the api debacle began) became a nightmare of downvote bots towards anything that wasn’t “Israel = good” in any way, and so many spam articles upvoted to the surface from random, unverified sources.
Edit to add: threat of defederation towards communities allowing or encouraging this behavior would probably be better, though.
