While it could be argued that rules against alt accounts are unenforceable, there's nothing unenforceable about rules against selling bitcointalk accounts on bitcointalk. These rules are enforced the same way rules against posting and selling child porn are enforced: You delete the post & ban the account responsible.
Easy peasy.
that would lead to:
- stupid people would trust trust/activity more and get scammed more likely
- mods / people like Quickseller would have a harder time to catch scams from such accounts
- people would get pm's bribing them to sell their account (or they would use gox leaked email list, bitcointalk public mails and so on -> more bitcoin related spam in my inboxes)
i always prefer transparency.
