alt Hacker Newsdownvoting a post doesn't require an LLM. an old-fashioned bot can do it just fine.
and there can be several motivations for it (e.g. downvoting a competition's posts, someone upset with how much pro-ai stuff there is on their favorite subreddit, etc.)
Frankly, I need to apologise because I must have totally skipped the "i suspect one of these teams has more bots than the other".
And agree that manual downvotes (or comments) are not always in good faith either (though I'd argue they're intrinsically still better than bot votes, but not as if you claimed differently :)
