You can argue that it's now a "new main account", but if that's the case, then Unknown needs to be able to provide the name of their old account to act as stigma, for lack of a better term. Otherwise Unknown remains a double account, no matter how sincerely they present themselves. Because we all know sincerity has nothing to bear on the issue.
