It is not against any rules to sell your account. If the person sponsoring the sold account still trusts the ratings of that account then there would be no reason to remove them.
The main reason is the original owner has sold the account. Such an obvious and valid REASON.
You have to understand -- Quickseller thinks accounts should each be treated as individual persons, and that the person controlling them is irrelevant.
It's a bizarre point of view that is unlikely to be held by most people, but it's his story and he's sticking to it.He/she is thinking wrong, I trust the 'person' behind the forum account not the account (itself). So he/she lost his/her mind, Quickseller take a hiatus....
