There are ways of determining which player is which, vaguely. You can keep track of reputation between rounds, and infer that player 5 from last round couldn’t possibly be player 23 from this round because that would require player 5 to have cooperated with more people than there are players. Alternatively, my bot could ensure the number of times its hunted in history is always a multiple of 17, and other smart bots could look for this.
