My best guess is that the PhF has control over an enormous herd of computers, which are all being reinstalled by a Ghost copy. The PhF included the RC5 client in the image, and is gradually spreading the image over the network. Not too many at a time, as that causes the network to overload.
If this is true, I have three questions:
1) Why doesn't he use his own E-mail?
I might be able to answer that: He/She could be affraid that cracking too many blocks would lead to disqualification, like happened to the Rabbit (although he used a trojan).
2) How does he change the E-mail address so often. I have about 20 computers running, but I wouldn't know how to change then, let alone such a massive herd.
Speculative answer: could quite easily be done with a logon script. Someone logs onto a computer, the script retrieves a new ini file, and there it goes again. Using more than one E-mail address can be accomplished by putting another ini file on every server (I presume such a herd does run on several servers, and for every server the clients only look on that specific server)
3) Why doesn't d.net track him/her down. That could quite easily be done. As the blocks must come from somewhere. If they come from one IP, or a small amount of IP's, than that server could be traced. I presume such a large herd does have a fixed connection to the internet, with a fixed IP address. If, however, the blocks come from about anywhere, it might be the work from a smartly programmed trojan. But than again, the trojan would not be smart enough. If the trojan flushed on a perproxy, and the perproxy flushes to d.net, then you seem to have the same situation as using a large company's herd.
Speculative answer to question 3: d.net has tracked him down, asked for his intentions, and the PhF politely asked not to publicise his information. another possibility is that d.net is still working on it.
Anyway, lots of speculation, and I might be totally wrong in the end.
If the PhF needs another E-mail address to fill up some nodes:
skiff@xs4all.nl. That might also be able to close in on team AT again.
