You can note markup in a code block --- 4 space indent.

    This normally would be *italicised*.

It's two spaces. Of course four will work as well, it just adds extra indentation.

Thanks.

Actually, it's not that obvious. It censored "Dirty Sanchez". I'm thinking it thought it was a person's name, and censored it for privacy reasons?

I suppose "pipe" can have an offensive/sexual connotation. Even if it doesn't so much today, perhaps it did back then.

My guess is that they just used a fairly large word list, which contained a bunch of euphomisms like Dirty Sanchez.

A good guess, that's exactly what I did.

IIRC, 'Dirty Sanchez' is a slang term for a sexual act.

"pipe" means blowjob in french. Maybe the filter dictionary is multilingual?

It can happen. A decade ago, Apple’s automated App Store processes warned me that “Knopf” was a dirty word in German.

(It isn’t: while “knob” can be translated as “Knopf”, the latter doesn’t have the anatomical meanings of the former).
