Sigma Social Game: Sigma "Anonymity"

Be clever, perceptive, cunning, and slick and put papers, documents or any objects without any personally-identifiable and traceable information that has you name on it so no one tries to "track you down" (i.e. unless by fingerprint DNA tracing), find you or figure out what you are doing in case they may find your items or materials; but you know what you are doing because you do not have any actual "personal business" or goals associated with your discarded random, optional paper materials.
