I would herewith like to suggest the removal of the following, three tags:


I just noticed (a day later) that those tags are gone from the tag-list. This makes me realize I probably missed something (and might be hitting a facepalm soon).

Each of those tags were used by 1 or 2 questions, which I edited to retag them using better-fitting tags. This resulted in the fact that there were no questions left that pointed to the tags I mentioned above.

Could it be that a tag is automatically deleted when there are no questions left that use it? Or, is this a misinterpretation and someone already killed those tags without leaving a note here (less likely)?

I'm asking to be sure I'm not posting superfluous stuff about things the system might be taking care of all by itself already…

Nota bene: I adapted the title to reflect the edit, as it might be useful (for future reference) to know if the system does this automatically.

Thank you for the edits.

Tags are automatically removed when no question uses them. This is done by a daily batch job, so wait 24 hours.

Additionally, there is a completely separate mechanism that hard-deletes tags that are 6 months old and used by a single question, without creating an entry in the question's revision history. Tags that have a tag wiki are exempt.

  • $\begingroup$ "Tags that have a tag wiki are exempt" That's different from what I remember. Did they add that exemption? $\endgroup$ – CodesInChaos Apr 10 '14 at 12:53
