RSO's give out their names and addresses to the public, but not their jobs. That is why, duh!, employers or workmates have to find out by feeding the names into the databases themselves.

And Trucker has well established that he has no other online accounts than GC, and that his boss has none at all. If so, he cannot be linked to his name or recent photo or whatever, unlike all those who have left exposed or discoverable accounts on AIM, MSN, YM, MySpace, LiveJournal, Facebook, etc. Even if false (which it should be - I cannot believe a business owner these days can do anything without an email address), as long as he sticks to that story here and truly didn't mix accounts together, ever, he wouldn't be traceable this way.

Admittedly, though, PJ should easily be able to get info because of their (illegal) infiltration into parole boards, but that is a different way of outing people and involves different skills and possibly different people.
