  // Need to work out where to hook this in to instead of just repeating
  setInterval(filterShows, 250);

  function filterShows() {
    $(".content li").each(function(index) {
      var $show = $(this);
      var showTitle = $show.find("h3 a").text();
      $.each(titlesToHide, function(_, titleToHide) {
        if (showTitle.indexOf(titleToHide) != -1) {
          $show.hide();
        }
      });
    });
  }
});

It now repeats in order to catch dynamically displayed content
