In the closing credits, the last names of some of the characters (Hafiz, Jack, Bill, Dr. Zahraa, Paul, Ali, Hammad, Beth and Pete) are redacted.
Also in the closing credits, various letters are shown yellow, among the primarily white letters of the credits -- these letters seem to form a cipher code:
CES?OAPCHFHTEOPISFMNADAMECAOREDATNRAYUURNQWKNUFRCOJRWRMDGSEHUWTOAKRA
(the question mark at the fourth letter in the code is used instead of a letter, as one of the redacted surnames, as mentioned in another trivia item, is colored yellow)
The film's closing credits declare: "Democracy only works if you do your part", and citing the website link - www.takepart.com/fairgame.
