Nobody has an update on @TMAN yet. I think @Lauda would have had some idea. Then again, those two really were part of the old guard so its possible that they didn't have any idea of each other's real world identities.
I'm not quite clear what you mean by Lauda's idea, but ... I don't understand what idea you mean, but ... I have repeatedly seen how TMAN is mentioned in such a context, so I think if someone with whom he traded had a connection with him, we would have known the reason for his absence long ago, and as I understand by "old guard" you mean adherents of crypto-anarchism?
