Can someone explain how so many R&S questions get moved to other sites?

They start in R&S, then end up hidden in Jokes & Riddles, Spam, Pets, Dining Out, or some other obscure location. How can a user do that to someone's question so it can't be answered, and why?
Update: See, now my question is in Jokes & Riddles, not R&S where I asked it.
