OK, just looking over everything here, I see a few things.
First, the original victoms of PhF received around ~10,000 extra blocks the first day, then on average 5,000 more extra for the next two days, then slowing down to 2-3000 extra per day until leveling out around 30,000 a day.
Now the lastest victoms like myself have seen very moderate amounts of extra blocks compared to the growth of the originals, I started out receiving 1,000 a day, and have grown to about 6,000 extra right now over the course of 5 days.
Now in my mind, this says a few things, 1) PhF is a coprorate guy, and has assimilated all the computers under his command and is continuing to expand much more slowly outside his department.
2) If PhF is a trojan, here's how I see it working. He sets up a custom written server program then releases a trojan into the wild which when started for the first time, contacts this custom server for an e-mail addy and settings. Once it's done that, the client continues to crack under that addy and send blocks to the round robin d.net servers. Very hard to track! Now on this server, he has a list of e-mail address's taken from this thread and/or Mika's page 1. Now the trojan growth is slow enough that he can watch the nightly stats until each person has enough blocks, then he removes that address from the list. If he removes all address's, then it cracks for
rc5@distributed.net, or to hide an exponential growth, he may have 20
rc5@d.net addy's placed in his list of e-mail address's. Using this method, it's very easy to control how many blocks everyone gets, although once the trojan sets up on a computer, it's not possible to stop it remotly, so we could see these for a very long time.
