What happens if users of @Arakbali, who create dozens of accounts on the BitCointalk forum, are sold exclusively.
The seller of the account cannot be trusted encourage fraud and spamer.
I don't think someone would buy accounts from a newbie user whom you've already flagged. Yet I think simply tagging them wouldn't be enough, tracking down those accounts he's selling is the best way I guess, hence making all of his accounts useless. Yet we cannot just stop them from doing such stuffs because Indonesia is a huge country and we couldn't know if he would have sell it to his friends or even to a stranger near him.
