Bizarrely, the reason I’d asked the question at all is because your comment that I’d replied to was rendered as a top-level comment rather than a reply to another comment.
So I was wondering if, rather than individual words being censored, entire posts/comments were being hidden, but not replies to them. I guess that’s actually just a bug or something, because I can see what you were replying to now.
I’ve had this experience of feeling like I’m not seeing the full thread / that someone is replying to something I can’t see a handful of times. It’s a weird one.
