Just as someone would not bother to answer an inappropriate question in real life (off the internet), the same reasoning applies when on the Internet. Some questions are simply inappropriate, either because it intrudes on someone else's privacy or someone else's rights. Other "inappropriate" questions are the same kinds that a grandmother, mother, teacher, pastor, or anyone in civilized society would think is impolite, rude, or gross. WikiAnswers has policies about questions, just as home, school, and churches have rules about what is--and is not--okay to ask.
WikiAnswers doesn't 'block' inappropriate questions, but rather stores them so no one can answer an inappropriate question that has already been asked. It is called a 'Catch-All', and it stores all of the inappropriate questions so when a user types in an inappropriate question that has already been asked and merged into that Catch-All, they will get an answer telling them that inappropriate questions are not allowed on WikiAnswers. In a way, WikiAnswers does 'block' inappropriate questions.
Supervisors can trash inappropriate questions to a catch-all category that houses inappropriate questions that are hidden and out of view of normal users on the site.
The majority of the time that Supervisors do not catch inappropriate questions is when they are using the Batch recategorization tool to move hundreds of questions at a time. If you see a question that is inappropriate, please report it via the red "Report abuse" button.

The reason is exactly what you said - the questions are inappropriate. WikiAnswers can be viewed by anyone in the world, and most are offended or appalled by such inappropriateness in questions, so to give them respect, they are put away to a good place. You do not need an answer to an inappropriate question.

Cyberbullying questions will get you blocked quickly and most times without warning, nonsense questions, and inappropriate questions.
The question you asked is inappropriate for WikiAnswers.
Because I enjoy helping people out in areas that I have some expertise. Sure, there are a lot of inappropriate questions that lead to some even more inappropriate answers but, there are also some very legitimate questions and it is fun to answer them.
When questions are cyber-bullying, illegal or 'inappropriate'.
Anything if its not bad or inappropriate. Knock yourself out :)
