One last Hail Mary

[shannonsequitur]

I don’t know anything about coding, but I’m posting this here in the hope that someone who does will have pity on me.

Last year, I found this user script (no name/contact info or even a date) for hiding Dreamwidth comments from blacklisted users. It works, but replies to the comments aren’t hidden, and I would like them to be.

Please help me?
