Ask the user above you one question (that is actually answerable),
and if they answer correctly, then they're innocent. If they answer
incorrectly, they're guilty. It is okay to not answer IF YOU ARE
OFFLINE, or else you are guilty. Please subscribe so you can get

user a question 1 time, as long as someone asks you "Where's
Perry".
