I have noticed today that we have a tag. It currently houses seven different questions on widely different notions of completeness.

Since there are widely different notions of completeness in mathematics, there is a lot of room for misuse with this tag.

I therefore suggest that we follow the footsteps of Math.SE and blacklist this tag altogether.

  • $\begingroup$ You might have already noticed comments under Todd Trimble's answer, but just to make sure - is this proposal about (completion) tag, too? $\endgroup$ – Martin Sleziak May 3 '17 at 6:26

    $\begingroup$ I saw. I did mean the completeness tag, though. It was a huge mess. $\endgroup$ – Asaf Karagila May 3 '17 at 7:06
  • $\begingroup$ It's not necessary, it only exists for completeness... Sorry, please publicly flog me; I definitely deserve it. $\endgroup$ – Jeremy West May 26 '17 at 1:52

This seems like a reasonable thing to do. If there are no objections, then I'll set the wheels in motion.

Update: After removing completeness tags by hand (from the 7 posts that used it), I had put in a request to SE Community Management to blacklist that tag. I've not heard back from them though.

Second update: As per Shog9's comment, the completeness tag has been blacklisted.

    $\begingroup$ Is (completion) being removed too - mathoverflow.net/posts/268770/revisions and mathoverflow.net/questions/268770/…? (I see that completeness has already been manually removed from all questions.) $\endgroup$ – Martin Sleziak May 2 '17 at 10:46

    $\begingroup$ Oh, good point. There are 24 questions currently with the 'completion' tag. It has no usage guideline. We should discuss. $\endgroup$ – Todd Trimble May 2 '17 at 14:39

    $\begingroup$ Regarding that (one) instance of the completion tag that was removed: it's been restored, as no one has expressed feelings that the tag is generally problematic at the moment. (Might be nice to have a usage guideline at some point though.) $\endgroup$ – Todd Trimble May 3 '17 at 11:58

    $\begingroup$ Tag is now blacklisted; it can no longer be used. $\endgroup$ – Shog9 May 16 '17 at 21:09
