I'm surprised there is this thread, even though buying and selling accounts is forbidden here.
It's not forbidden to buy/sell bitcointalk accounts. But these things are discouraged by community and people involved are risking to get red trust rating.
So, does that mean I can create 100 accounts on BitcoinTalk and sell each of them for like $10. Thus, I'd be making $1000 without having to spend any money?
I don't think that someone would buy Newbie account for 10$ when they can just create new account themselves. When Merit system was introduced I think that account sellers only can benefit by selling accounts higher than Jr. Member, though I see Jr. Member accounts for sale sometimes.
