Is there a complete list of blacklisted words for titles?

I think there's:

  • problem
  • error
  • issue

But I'd like to be sure.

  • So, network-wide or just Stack Overflow? Because I think the ones you listed are SO only. Also, [closed] and [migrated] are blocked, too. – a cat Nov 2 '11 at 20:36

    "Error" and "issue" are not blocked (yet – let's keep it that way). – slhck Nov 2 '11 at 20:45

All Sites

  • [on hold]
  • [closed]
  • [migrated]
  • [tag] at the beginning of the title (tag can be (almost) any string)

Trilogy Sites (SO, SE, SF)

  • problem
  • help (only at the beginning of the title, or if followed by  with; ref)
  • question (confirmed on SO at least)


  • Feel free to expand – I don't want to go fill every site with test questions :P – slhck Nov 2 '11 at 20:45
  • It seems you can test this without actually posting a question: just typing in the title and changing input focus is enough to trigger an AJAX validation check. – Ilmari Karonen Feb 14 '14 at 13:26
  • @IlmariKaronen Yes, that's possible ever since they revamped the error messages. Before you'd have had to submit the question in order to test this. – slhck Feb 14 '14 at 14:50
  • FWIW, currently, it seems that some of these words are only blacklisted in short titles. For example, the title "asdfghjkl asdfghjkl problem asdfghjkl" currently triggers the blacklist on SO, but adding one more "asdfghjkl" at the end allows it to pass. (I seem to recall seeing this confirmed as a deliberate feature by Shog or someone else at SE, but I didn't manage to Google it up right now.) – Ilmari Karonen Jan 2 '19 at 14:40
  • @IlmariKaronen regarding the short title, the filter is only applied if the title is shorter than 40 characters. – Meta Andrew T. Apr 6 '19 at 6:22
