On Drupal Stack Exchange, we had tags like 5, 6, and 7 for the Drupal version. All in a sudden, since today it is not possible to edit questions with those tags, even as moderators, because they aren't allowed anymore.
We have those tags since the site was in beta phase, when Stack Exchange decided not to allow tags like drupal-6 because users would have picked them just for the fact they contained Drupal and the question was about Drupal.

Are those number-only tags still allowed, or is Stack Exchange blocking them because a bug? Should we use a different tag schema for those tags, considering that drupal-?\d+ tags are black-listed?

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.


This should be fixed. I don't know why the change was made, so until we can figure that out Michael has rolled it back.

If we have to restore it, we'll try & post something ahead of time explaining why.
