From what I've seen, it just seems too implausible to me even beyond the practical considerations. Satoshi was carefully guarded, but I suspect something not that far off from his real personality shone through in all of his posts and emails. Maybe even something very close to it. I have no idea what his moral character is, but my gut feeling is that he's just not the sort of person who would work as a bogus pharmaceutical seller, spammer, drug trafficker, arms trafficker, and murderer. Of course I can't possibly claim to know this with any certainty, but I just have the feeling it's very unlikely he's anything close to a Pablo Escobar-type.

My guess is he's a single individual whose real identity has never been publicly suggested as a serious Satoshi suspect.
