Why are there vulgar questions in the etiquette section of Yahoo! Answers?

Are these people purposely trying to gross me out? Shouldn't the moderators just remove all vulgar questions in the etiquette section, such as "Are you a bed wetter?" or "Have you ever took a dump in your pants?" These questions are simply disgusting. If you think it shouldn't be removed, and think it's actually funny, then honestly tell me why you think it's so funny. I would really like to know.
