Based on the comments above, I think I've got a fairly good guess who you're talking about. And if I'm right, I wonder if it might be worth going public (on LJ, that is), so people can know what he's doing and--one hopes--refuse to do business with him in the future. I realize his customer base (again, assuming I'm connecting the dots correctly) is wider than just your friends list or mine, but we might make a dent, anyway...
