Encourage Traitor Teams? (new syndie item)

[babywrangler85]

I like the way tg(?) implemented this in that traitors all started with a couple code words and responses to those code words that could be subtly worked into conversation in order to allow mutual identification. My concern with your suggestion is that it doesn't allow a traitor to purposefully avoid identification by other traitors, which is important because there's actually an objective traitors can get to kill all the other traitors.
