I don't remember the entire past conversation about this. But one thing it does, IMO, is create too many possibilities for information to be passed around freely with no consequences. Spying is already easy enough. With this, any time you send a message, it can be anonymously leaked bg anyone who gets is (or any infil). We don't need people being able to anonymously spread information (or disinformation) on such a wide scale.
But that's just my opinion.
Make a skill based chance for the senders identity to be revealed.
