David, you made a little bobble in a thread. You called Bill "Scott". I thought it was an accident, so I mentioned it to you in a PM.
Then you PM-ed me back that you had it on good authority that MarbleMansion was Scott Birchfield of Maine. I told you no. You didn't seem to believe me but you did edit the spot where you called Bill "Scott".
I DID try to keep it private, and cover for people [edit: by "cover" I mean "minimize potential embarrassment"], but you couldn't/wouldn't tell me what your good authority was and I was concerned by how far the rumor might have reached so I posted that one "nip it in the bud" thread about the rumor. And I thought/hoped it was over. But it very understandably shook Bill.
Rumors suck.
Bottom line: MarbleMansion is Bill. He is cool. He has contributed to marbledom in a positive way.
Pavcraz is Scott Birchfield. He has perpetrated major frauds. He is not a positive contributor to marbledom. He is endless fodder for threads like this one.
