(yes, and I know that request isn't creepy at all... but there is no way I'm posting a solution for him to read... and I'm only going to respond to people with a posting history that is compatible with my concerns)
Does it involve plastic surgery?
You raise an interesting point. All that he had to do was start a new business and not let anyone know that he is running it. BUT he is too full of himself, too narcissistic to have the willpower and/or restraint. It is not in his psyche to do that.
He already had this chance with the mineral thing and obviously he couldn't survive without thoroughly explaining how he's totally not involved with it and without being an admin on the new forum (which is still "Integrating accounts", whatever that means).
