What do you mean "zombie" initiates? Inactive?
Sorry, I should have been more clear. Zombies are users that never posted, never voted, and never really used their accounts.
I think we could look into providing you a batch of more specifc data. Id have to think a bit on how to present the info so that it doesn't tell you each nodes rep exactly, but does allow you to do your stats. If you can suggest forms of the info that would be sufficiently useful to you but sufficiently anonymous that I can give them to you Id be happy to do so.
