It sounds like you believe that high ranking members of BCT are not scamming too. Higher probability as the were farming many BCT accounts. BCT rankings has nothing to do with managing a bounty. So your saying that BCT should force projects to use managers just because they are from ranked members of the BCT community? You opinion sound very biased indeed. I hear a lot of make them pay!! Make these particular people rich, but little about how to protect bounty participants.
I am not saying that higher ranking members are all saints. But it is difficult for them to get involved in scams because they don't want to risk their reputation which was earned through hard work after so many years.
