Yeah, this is not gonna happen. Since buying/selling accounts is usually for shady reasons
This is not true in all cases. What about those who only need it so they can get into bounty and signature campaigns in order to earn? Or you think there are no members like that?
1. I wrote "usually". That means most of the cases, but not all.
2. I do expect that some want to buy accounts for campaigns. I also expect that most of those buying accounts for using them in bounty campaigns will actually spam.
A honest user can learn his way in bitcoin and bitcointalk ranking up normally.
Taking shortcuts will lead to problems and, even if the reason is bounties/campaigns is still shady; just imagine (paid) posts made by a high rank account talking about things he has no idea at all (of course, I know, it can happen sometimes even with honest/not bought accounts). Then, if the user is knowledgeable, the bought account may be a secondary account. Using multiple accounts in campaigns is prohibited; using multiple accounts in campaigns can easily lead to low quality posts. Hence, again, shady.
I hope you can agree with all this.
