It might be very good to purchase reputable and well known member's account to use his reputation to scam people. But if the sale is known and something is out of ordinary, it loses whole point of it.

Each account have unique personality that reflects the user who controls it. Someone else using other account will be just wrong. Just imagine someone else using Atlas account! And it is hard also as I struggle to give each of my sockpupets here a different personality

edit: selling soul is just as big scam as selling BFL or any other Bitcoin mining ASIC chips. Both of them does not exist, besides BFL is additional scam contrary to soul who just is religious misconception of cognition.
