Please don't automatically assume the worst motives.
We couldn't care less if you use the word or not. But we do care when we spend hours of costly time dealing with ad services whose machine learning systems don't understand context. They have sent us a warning about "sexual content" at least three times in the last year or so for that word.
There's time involved submitting appeals which usually fail (because they again use machine learning), then appealing repeatedly until a human reviews the page. It makes no sense to spend hours on this again and again, when 5 minutes to set the Xenforo word replacement prevents the problem from happening again. And it solves the problem without changing the meaning of posts one bit.
