I've noted myself and other users have also seemed to note that stories can no longer be tagged with the "7" tag. Did I miss a memo somewhere?

I tried editing a question with that tag, and I got an error about that tag not being allowed. I will check what happened, but it seems the software running Stack Exchange doesn't allow that tag in the questions. I have a vague idea of why this happens; I just need to verify it.

As per Are tags with a name made of just numbers still allowed? this has been now fixed. If they change the code, and introduce back this behavior, they will also make a post on the main meta site to explain why they introduced back this limitation.

  • Yes, I noticed. I asked a question on the main site to understand if they don't want us to use number-only tags (since not even 66 is allowed), or it is just a bug they need to fix. 7 is not black-listed, so it's not an issue only on DA.

  • Indeed, and 8 still works fine it seems

  • Actually no it doesn't, so yeah this is definitely related to numeric tag names

Sorry about this; this was my bad. It was impacting an API. I verified that we didn't have pure numeric tags on some number of sites, but I obviously failed and didn't thoroughly check all of them, which is my error. I will find another approach for the problem that I was trying to fix. The code has already been reverted. Again, sorry.

  • Not to hijack your answer, but does this mean you "test in production", or rather that you "don't have a representative test environment"??? Btw, are there any such site as X.stackexchange.com, whereas X = unittest, integrationtest, volumetest, useracceptancetest, etc? Feb 21, 2017 at 20:02
  • @Pierre.Vriens no, it simply means that we can't anticipate and test for every single scenario. We do indeed have a representative test environment, but I'm not telling you the url :) Feb 21, 2017 at 21:14
