I have used @Thariama solution in the past, but I have compatibility problems with IE6 (I still needs to support this dinosaur).

If the item repeats, so remove it from ul. It works with dynamic added li.

            var seen = {};
            $("ul#emails_exclusion_list").find("li").each(function(index, html_obj) {
                txt = $(this).text().toLowerCase();

                if(seen[txt]) {
                    $(this).remove();
                } else {
                    seen[txt] = true;
                }
            });
