Why wouldn't you just say bullshit? You didn't even write it in a self-censored format (e.g. bulls**t), you just wrote the actual word with a some funny characters in place of the actual letters.
Some online platform automatically censor or bring about negative repercussions for a given set of banned words. I realize HN is probably not among them, but I still formed this involuntary habit. You have a point tho. It does look much better in what you call self-censored format.
