Arbitrary anti-abuse rules typically have limited upside and significant downside. HN already has a lot of anti-abuse baked in, much of it highly dynamic, and as dang's said here, largely based on member-based actions. Downvoting and flagging content really does work, even if it's occasionally slow (a few hours to accumulate enough flags to down a comment or new account). If that's not fast enough for you, or you see a newly-emerged problem, email the mods at hn@ycombinator.com, with a clear and concise statement of the problem and links to examples. More on that in an earlier comment, including some research tips: <https://news.ycombinator.com/item?id=42571073 https://news.ycombinator.com/item?id=42571073> Most of the time I've reported spammy or abusive accounts they've already been marked as such within the system. Maybe one in ten seems to be novel.
