But https://www.hnreplies.com works fairly well.

I have found that it forgets about me, after a while, so I stopped using it.

Every now and then, one of my downvote stalkers likes to go to an old comment I made, and write an insult. I assume that because the comment is so old, the post defies the Banhammer.

I don't mind missing those, and I guess it makes them feel better about themselves, so it's all good.
