Hello, I hacked you some time ago. I haven't decided whether or not to do anything with your information yet...

Let's play a contest of riddles, just like Bilbo and Gollum, or Odin and King Heidrek, or Oedipus and the Sphynx. It's been a part of our histories for as long as warfare. If you answer them correctly, then maybe I'll let you go, if not, I'll release your information for the whole world to see.
What do you say?
