If you refer to Bitcointalk and other forums, that's a different thing, I've seen a lot of other existing forums, but they're not the same as the ones here, whether it's the accounts that operate, how to post, discussion boards and so on.

Back to the point, you can't sell an account here to another forum, account login access is different, different forums have different login access methods, so you can't sell a Bitcointalk account to a neighboring forum.

Unless: you sell the account to your neighbor, but the account remains in operation here, in such cases 30/70 DT will act, on a case by case basis, in assigning trust to the account that has been sold or bought, which is certain action exists, if found out.
