Basically, the person above you will post something that you might have done (usually starting with "Have you ever..."), and you will declare yourself guilty of doing that thing or not guilty of doing that thing.
Here's an example:
Person1:"Have you ever taken money from someone without their knowledge?"
Person2:"Guilty. Have you ever let out a person's secret in front of that person?"
Person3:"Not guilty. Have you ever talked to yourself?"
Person4:"Soooo guilty. Have you ever..."
So, time to start!
Have you ever followed someone without them knowing?
