??? I can't say "smut" on Amazon?

Recently, I posted a book review on Amazon, which included the phrase “gratuitous smut”. When the review appeared, this had been changed to “gratuitous …”.

:confused: Since when is the word “smut” something that has to be censored? I can understand that they would censor curse words or really crude language, but it was the book’s crudeness that I was objecting to, and they censor that! Ironic, to say the least. Not to mention that that ellipsis now gives the impression that I said something “smutty”!

What is wrong with the word “smut”? (Please, please, you don’t tell me how much you don’t object to smut itself…)

I think Amazon just tries to be completely un-offensive, and therefore censors the dumbest things that could possibly be offensive in any way.
Personally, I don’t see how anyone can be offended by the word “smut”, but it wouldn’t surprise me.
