I suggest to rename the tag divisors in a way which distinguishes it more clearly from divisors-multiples.
The tag-info for divisors (revision history) clearly says:
For questions related to divisors in the sense of algebraic geometry (Cartier divisors, Weil divisors and so on). For question on divisors in the number theoretic sense please use the tag divisors-multiples.
Still, some people might not notice the tag-excerpt, and if they look only at the name of the tag they might assume that the words is used in number-theoretic meaning. (For example, the questions which are currently tagged divisors+nt.number-theory are most likely mistagged. And there are a few more examples of questions which originally had (divisors) tag and it was later corrected to (divisors-multiples) tag.)
I am not really sure what would be a good name for the tag. So I'd be grateful if you have some reasonable suggestions in comments.
I would probably suggests simply divisors-algebraic-geometry following the title used in Wikipedia article Divisor (algebraic geometry). I have seen that Ricardo Andrade suggested scheme-divisors in chat. Joe Berner mentioned the (already existing) tag algebraic-cycles, but immediately added also that algebraic cycles and divisors are not the same thing, so these two tags should stay separate. See also his comment below this post.
A few years ago a separate question about divisors tag was posted: What subject specific tags could replace the tag 'divisors'? However, it did not generatedgenerate much discussion (only two comments).
