there are other forms of filtering/ rate limiting like by reputation, HN does this already to some extent for new users < 500 . Recency of reputation changes can be factors so historical accounts don't accrue a lot of value for bots to buy. We will downvote spam or low quality content anyway . Accounts (users or bots) with poor rep can be more harshly restricted. Ultimately does it matter if a human is actually posting if the post is insightful / useful ?
