That message is received either when a user is trying to access a part of the site they don’t have access to (such as the Premier Poohbah forum before qualifying) or when they are trying to access a thread or post that has been removed.
Like other forum software messages, it makes no judgment or criticism of the member who receives it and it does not mean a member is in moderation. If you were in moderation you could not have posted this thread or responses to it without a moderator approving them, meaning there would have been a delay in posting.
