I read a few discussions on meta somewhat related to this question, but I'm still unsure about it.
I've noticed that one user has been submitting a large number of edits where he or she simply added one tag to the question (in fact, he or she added the same tag each time which sort of raised my suspicions). I would classify the tag as "mildly relevant" to the problems but definitely not "essential". I ended up approving the first edit and skipping the subsequent ones.
For a frame of reference, I would classify the tag of "inequality" as "mildly relevant" to the question:
Question 1. How does one use the $\varepsilon$-$\delta$ definition of continuity to prove that the function $f(x)=x^2$ is continuous on $\Bbb R$?
In other words, I understand why one might include this tag since this proof involves the manipulation of inequalities. However, I doubt the addition of this tag would draw the attention of otherwise uninterested users.
In contrast, I would classify the tag of "algebraic-geometry" as "essential" to the question:
Question 2. If $f\in\Bbb C[x_1,\dotsc,x_n]$ is irreducible, how does one prove that $\Bbb V(f)$ is an irreducible variety?
Does anyone else skip or maybe even reject edits that only consist of the addition of "mildly relevant" tags or am I over-thinking the situation?
