I know this is likely a duplicate of How should we handle users who generate consistently low-quality and off-topic questions? But, that seems like a discussion of a more egregious offender than the person who is irking me.
There is a particular poster who is using up all of my close votes in a day by asking the same types of questions over and over again.
These questions are not particularly "low-quality" but rather asking about punctuation and grammatical usages that should be easily found using standard English resources. I have left this person multiple comments to this effect, but they continue in spite of this.
It wouldn't bother me, except that this person posts many, many posts which I'm encountering in the review queues. [They probably hit the daily max and, despite that volume of output, their reputation has remained in the 400 range.]
I am deliberately trying not to mention the person directly or post an example question, here yet.
My issue lies in the signal-to-noise ratio. This poster likely has a few valuable posts, but given the sheer number of posts they are making, it's eaten a considerable amount of my time casting close votes, etc. It makes me default to assuming their question is not valid.
