I think the ban came about due to a threat of sanctions issued by a couple of Librarians, who were concerned that the supply of one of the dietry staples for LSF Staff could be comprimised if there were to be a Continental Market Upswing.

Word has it, that checkpoints have been established just outside Burton-On-Trent (Home of the illustrious Nectar) to determine the exact destination of every consignment, With reports of a group of activists known as the "Pink Bunnies" threatening "Ultimate Sanctions" against anyone foolish enough to try to divert any of this commodity. (I believe there was a reference to calling in Ms Thrashbottom or some such person to police these measures).

Meanwhile, A statement was released from the Pink Bunnies secret H.Q. that the Vegemite substitute only came in to existence due to the effectiveness of the sanctions of this shadowy group in denying widespread distribution of "The Real Deal" A little like Methadone is to Heroin!!!
