As part of my daily routine, I flag deleted questions on Stack Exchange. Usually, I see something like this:

enter image description here

And to flag a deleted post that I can't see, I have to open Postman and fake the POST request for flagging. This takes a lot of time and is inconvenient.

I want a userscript/extension that:

  • Adds a flag button to deleted post 404 pages
  • Ideally brings up the standard flag dialog, but it absolutely must allow me to input custom text for a 'requires moderator attention' flag. I don't really care about other flag types, so the standard dialog isn't required
  • Ideally it wouldn't require me to authenticate with the API, instead using the standard POST requests available inside the page (with my fkey).

Is there a script that can do this?

    Regarding your second bullet: the only flag option for deleted posts is "other". – hichris123 Nov 27 '14 at 23:47

    Is that allowed? Is it the daily routine of all SE moderators? If so, why doesn't that functionality exist? How do you find a good reason for flagging if you can't see the content any more? – Thomas Weller Jan 30 '15 at 22:14
  • @ThomasW. It's allowed by the system, and it can be useful in a couple cases, primarily when you want to flag a user for something and their only content is deleted. It's not a daily routine for everyone, it's just a hobby I have. – Undo Jan 30 '15 at 22:27

if ($('h1:contains(Page Not Found)').length > 0) {
    var postId = document.location.href.match(/questions\/(\d+)\//)[1];
    var $a = $('<a />', {
        text: 'Flag this question',
        css : {
            float: 'right'
    var $spinner = $('<img />', {
        src: 'http://i.imgur.com/YPmA6Jk.gif',
        css: {
            position: 'fixed',
            top     : 0,
            right   : 0
    $a.on('click', function () {
        var flagMessage = prompt('Enter flag message here.');
        $.post('/flags/posts/' + postId + '/add/PostOther', {
            fkey     : StackExchange.options.user.fkey,
            otherText: flagMessage
        }, hideSpinner);
    $('#mainbar-full .subheader').append($a);
    $('#mainbar-full .subheader').append($spinner);


    function showSpinner() {

    function hideSpinner() {

Above userscript adds a link to the right of the header of every 404 page that allows you to flag the question with a custom flag via a simple prompt() call.


  • I've noticed that the userscript doesn't work (anymore?) in case the removed question is removed due to spam flags, while it does for deleted-but-not-as-spam posts. – ProgramFOX Jul 7 '15 at 15:51
  • Well, the test is for "Page Not Found" to be on the page (in an <h1> element). If that's different, then the userscript would indeed not work. – Madara Uchiha Jul 7 '15 at 19:02
