I've been under "rankban" for at least a year, if not longer. This means that my posts, even if they get a lot of upvotes, fall to or near the bottom. I don't really care, and while I could use sock puppets to get around that, I'm too old for that shit and I don't really care. Still, it's irritating.
I've used HN Search (https://hn.algolia.com/) to verify comment karma and validate my suspicion.
I'm also on "slowban", as Hacker News performs worse when I use it while logged in than when I do so in incognito, logged-out mode.
It's dishonest bullshit. My main reason for continuing to comment is (a) to spite the moderators and (b) because there's a certain joy in getting +10 karma even when your post falls to the bottom.
