I think it was some lingering sense of basic decency. My bad. When he started posting all over unrelated G+ posts (okay, not important stuff, but pictures of cats and things for family that I had semi-public), I think I can safely say that he's not worried about these sorts of boundaries anymore.
I've given him a URI for downloading the tarball. What he does with it is anyone's guess.
This was willm (redacted again at the request of forum staff), owner of a starwars game, gundam seed, and zero. I suspect people could do business with him just fine as long as clear contracts, expectations, and boundaries are set and never crossed. I sure as hell don't want him on any of my systems though.
Again, for those who are vaguely worried about all this: his data is fine and safe, and he has full access to it. He's just been an utter jackass.
