‎​‎​‎​‎​‎​‎​‎​‎​‎​‎​‎​‎​‎​‎​‎​‎​Prior to an edit, this question was posted with no content in it, both in the title and the question body.

Screenshot of the current post before it was edited. The Meta banner is visible as is the score and other elements of the page but the title space and post body are completely empty of text, showing only the post notice banner stating that the post was migrated from Meta Stack Overflow

The explanation to reproduce is provided in Temani Afif's answer.

Since this was discovered, similar text fields around the site have been found to have similar issues and they are outlined in the answers below.

Note from Catija:

While we appreciate all the effort y'all have gone to to test and find places this is possible, we'd like this question to be understandable so that seeing it doesn't cause confusion. Feel free to add additional information in answers but please leave the question itself as-is.

As we can not see, I was able to submit an empty question.

To reproduce it:

  1. Submit a question with a content
  2. Right after the submission, edit the question to remove everything and include invisible zero-width spaces.

Edit the below snippet to be able to see the spaces (they will show as red dots if you are using Chrome)


The system didn't allow me to submit the question initially due to the quality check but there was no quality check after edits.

We can, by the way, submit empty answers without the need of an edit after (see this answer).

    I can see this is going to be a real pain to stop people doing this, but also I suspect that it's going to be unlikely be abused. If anything, if someone does this with malicious intent they'll likely just going to get stern words from the mods. Though, I won't lie, the whole thing is really amusing. It would be even better if we'd all lumped in to post "blank" comments and answers. ;) – Larnu Jan 6 at 21:33

    @Larnu and using blank usernames ;) – Temani Afif Jan 6 at 21:35

    That is the stuff of nightmares. – Larnu Jan 6 at 21:36
  • Don't focus too much on visibility. Although the content isn't visible, it's clearly visible that (on the main sites) this would be deliberate malpractice, making it not different than any other malpractice, which community moderation is perfectly capable of dealing with. – Gert Arnold Jan 6 at 23:06
  • 1
    @GertArnold why waiting for moderation intervention when we can prevent this from happening? Few more tests on the content should do it. – Temani Afif Jan 6 at 23:09

    “if you are using Chrome” — Works in Firefox, too, at least using Nightly 86.0a1. – Sebastian Simon Jan 7 at 5:33
  • It's not a real pain to stop people doing this @Larnu alter table Posts add constraint ChkPostBodyLength check (datalength(body) > 100); (repeat for all fields with user input text). – ben is uǝq backwards Jan 7 at 10:50
  • 2
    @benisuǝqbackwards a zero width unicode character has a value of 2 for datalength, so 50 of them, and done. But that would also force users to post comments that are 50 characters long. That is far from desired. – Larnu Jan 7 at 10:54
  • The length could be different for different fields @Larnu, but you're right about the spaces having a length. You'd have to replace them first before performing the length which would make longer strings (i.e. posts) a real pain at scale. – ben is uǝq backwards Jan 7 at 11:53
  • 9
    Stripping leading/trailing spaces (including zws, zwj, etc) was routinely done on submission for years, @ben. It led to some other obscure bugs, so I'm guessing someone fixed them by moving the check without considering the implications. – Shog9 Jan 7 at 15:20

    Good job! I click "Looks OK" because it has demonstration value and funny (later it will be likely deleted). – peterh - Reinstate Monica Jan 7 at 0:32

    Only mods can delete comments (maybe if it gets 6 bad-guy flag, then @Community deletes it). Only questions and answers are moderated by 2k+ guys if they get VLQ/NAA flag. – peterh - Reinstate Monica Jan 7 at 0:44
  • I am not enough brave to play with it, but maybe we could create empty tags or wikis/excerpts, too. – peterh - Reinstate Monica Jan 7 at 1:14
  • @peterh-ReinstateMonica yes works with wikis too ;) still trying with tags :p (didn't succeed) – Temani Afif Jan 7 at 7:31

Oh boy:

We can use it to raise empty custom flags. Empty tag wikis, too.

I can also use this method to screw up my "About Me" section, e.g., remove the text "Your about me is currently blank", and the "Apparently this user prefers to keep an air of mystery about them" that y'all see:

    I'd say that this is by-design. Users should be able to have an empty "About Me" section, if they like. – Cody Gray Jan 6 at 23:13
  • 4
    @CodyGray They can, but empty profiles always show the "Apparently, this user preferred to shroud themselves in a veil of mystery" or the like. – Ollie Jan 6 at 23:14
  • 12
    Yeah, but what if I don't want that silliness? Seems reasonable to allow its removal. What I'm saying is, there shouldn't be a content requirement for profile pages like there needs to be for posts. – Cody Gray Jan 6 at 23:27
  • @CodyGray By all means go ahead and make an FR, but I'm just posting the bug according to the current settings. – Ollie Jan 6 at 23:59
  • 12
    What I'm saying is, I disagree that this is a bug. – Cody Gray Jan 7 at 0:13

Thanks to @ppwater, the tag now has an empty excerpt and wiki. See the tag info page.

There's no clickable area to this post from the 10k tools' Delete Votes page (there's an answer here with a pending delete vote).

Unclickable delete vote entry

Even on posts I'm unable to vote to delete/undelete, I can still click the link to hop to that post from this entry.

Not super unique (I mean, we already know the title is unclickable) but I see other answers documenting places where this affects accessibility and figured I would add this to the list.

Search engine, notepad, notepad++, IDLE, pycharm, etc. None of them rendered the actual dots.

Also, it's not possible to put your profile name as these characters. This is what happens when you try:

That doesn't mean answers and questions should work the same way, though.

Lastly, this:


Why do you have to do this to me?

Also, I've tried this on codidact


As relaxed as chatroom tags already were, we can also have empty tag identifiers.

The same can't be said about tags created through the [tag:...] format.

It turns out I can have zero-width characters in my password, although I also need to add one letter and one number.

One can use Unicode combining characters to produce an almost empty display name.

enter image description here

Try it yourself:

const textarea = document.querySelector('textarea');
document.querySelector('button').addEventListener('click', function(e){
Select all and copy in the textarea below or 
press the Copy button to get an almost empty 
display name you can set. <br>
<textarea readonly>̣̣̣</textarea> <br>

  • It's Unicode combining characters, right? – iBug says Reinstate Monica Jan 7 at 17:48
  • @̣̣̣ Yes. I see you've tried it. – iota Jan 7 at 17:48
