I'm burninating distance-geometry. It has 4 questions (now 2), and has a tax excerpt. The problem is that its scope (as described in tag info) is very narrow while the title sounds very broad. It results that the questions do not fit the restricted scope, and it just makes an additional tag in a subject which already has several tags: mg.metric-geometry, discrete-geometry, etc.

I will add that distance-geometry was created in September 2018.

@MartinSleziak @MartinSleziak How do you explain that the tag was created in 2018 while the question mathoverflow.net/questions/352785 was written in 2015 with no edit since then, yet has the tag?

@YCor The question you have linked was posted on February 15 2020, maybe you meant some other question.

BTW I suppose you meant manual removal rather than burnination. (To burninate a tag, you'd need help from Stack Exchange staff.) Meta Stack Exchange: What does it mean to “burninate” a tag?

@MartinSleziak oops, I meant this one but read 15 as 2015...

That happens. I think I recall some discussions where the same problem lead to some misunderstanding.

It is easy to misread Feb 15 as Feb '15. (The fact that Stack Exchange shows year only for older questions has some disadvantages and some advantages.)

... combined with the fact they show only last two digits of the year.
