That presumes downvotes represent honest disagreement, which we both know and I have proven they don’t.

Because now one asshole with 500 different alts across the fediverse can take any post he wants and massively downvote it, enforcing consequential action against opinions he doesn’t like, and no one is the wiser.

That’s why we deal with the one having 250 upvotes, and give 500 upvotes to whoever disagrees with it, letting that opinion rise to the top instead.
