I believe they are saying that the commenter looks a lot like karma farming with an llm, it leaves a lot of comments like this one

What benefit could one possibly get by farming karma on site like hacker news. It's not like one can gather followers or something. I'm always mystified by folks who do this. Would love to understand the motivation.

Having multiple high karma accounts is useful in astroturfing, as moderators are (rightfully) more lenient on established community members than new accounts.

Same thing is widespread on reddit, usually for pushing specific products/projects/organizations into the limelight. Landing on the frontpage of reddit/HN drives huge amount of traffic, so obviously "optimizers" learned this, and started priming accounts for future vote-rings and what not, but they need to mix in real-looking content between the pushes so the accounts don't get banned.
