Realistically speaking - no - the way you put it.
But my objection was more towards the imposter being in control from the beginning. I just don't see that.
We can agree to leave his family out of this, and go back to the main question:
"Did Bruno voluntarily give access to his account?" [for money or without]
My line of thinking indicates a solid "no", for various reasons, the main one being the failed Gleb account sale.
But since we are at it, how plausible would an inside job scenario be, just to smear Bruno's account and contribution, for constantly busting scam-friendly alt accounts?
Pretty hilarious bud, I know.
