alt Hacker News> If you can herd a bunch of karma via botting, you can then [maybe] use that karma to influence all sorts of things.
How? Karma on HN is not like Karma elsewhere. The idea of [maybe] monetizing HN Karma reads like the old southpark underpants gnome meme[0].

Assuming karma helps you get posts on the front page (does it?) then karma helps spam.
At any rate, HN attracts trolls. I'm sure it will also attract trolls who use AI to increase their rate of trolling.
