However, it doesn't seem like any actions are going to be taken to further help account sellers. And I don't see any good reason for why the forums should actively assist account sellers. Allowing them to stay is enough.
I'm inclined to the same view. Why should the forum change anything in order to protect the parties to what's a pretty scummy activity anyway? The only change I'd support is tagging of accounts which have been sold so that new users are aware the person posting isn't the original account holder (old users probably know anyway, by the change in posting style).
