It seems to me that the risk TubaDiva took in offering to allow The Man with the Golden Gun to remain because of 9 years of good behavior is clear: it sends the message that all you have to do to avoid a ban is to behave well for about a decade.
If that were allowed to become the rule, imagine – we’d have all sorts of people behaving well for decades, and there wouldn’t be a damned thing we could do about it!
