I know a website that selling Bitcointalk account in bulk including higher rank member with positive trust.
Maybe we can tag high rank user that recently just active for the purpose of participating on this campaign.
I also think that you should expose that website.
For the reason that I don't want newbie or other low rank user will have the idea to buy there just like what lovesmayfamilis point out. I will give you just a hint, You can easily see it when you search Bitcointalk Account for Sale. The website that offering it was a trusted site because they have built-in escrow system so everyone can easily trade without the risk of scamming other party. Most of the account for sale there is a gaming account.
It's up to you if you will exposed it here since those crazy account seller can't be stop no matter what we do here.
