    /*--------------------- Hide All Blacklisted/Deleted ----------------
    |  This block contains the code to hide all blacklisted or
    |  deleted items from the user watch page (called messages on the site)
    |  or from the gallery when browsing by tags. It functions by first
    |  expanding any 'more' expandos, then looking for any items that
    |  have the css class called 'blacklist-overlay', or for deleted items,
    |  it looks for the title of the item to be 'Item has been deleted'.
    |  It then sets the css display attribute for these items to 'none'.
    |  This block uses the 'pause' function, which is provided by the functions
    |  include in the meta block. Performance metrics are printed to the pages
    |  footer below the existing text.
