Or he's trying to be this board's version of "The Poster With No Name" and just doesn't know how to remove his handle.
TPWNN? No, the page greets me with "Hello Ryu", not a default "Hello Chummer".
Another take:
The quotes point to someone with military/intelligence background. Politically informed about Middle and North America. Able to hack Jackpoint or to arrange for it to be hacked. Hestaby seems to be a major concern, and A.Nonymous knows about the dark side of Dunkie.
Great dragons and their ilk have yet to accept that the world moves faster than them, and it has no regard for their plans. They may think long-term, but humans are unpredictable and a bit crazy. We’ve also been playing this game for millennia without end.
This sounds like first-hand experience with both dragon plans and spy games around them.
[spoiler]My current guess is an old friend of Damien Knight, if he is still alive. An experienced spymaster with access to DK´s matrix specialists, Roger Soaring Owl has contacts all over the NAN and is one of the old-timers with unknown agenda. He would also be able to comment on the threat statistics for Lesker if KE did the job.[/spoiler]
