I am the person who downvoted. I am not afraid "to come forward", as many have speculated. I don't believe that I have done anything wrong, and I am rather certain I have not broken any rules.
The short is that I think that all those answers are bad. I'm not interested in hurting any persons rep or feelings.
My reasoning for thinking these answers are bad varies from answer to answer.
But as a blanket, I think that answering questions that are clearly unclear is not answering in good faith and harms the site, that is quite clearly bad.
I also do not like low-effort fastest-guns-in-the-west type answers. These answers to me seem to just exist to catch random upvotes on a question likely to hit the HNQ. They don't feel like they have even earned the space to exist.
This makes questions like this a perfect storm for answers that I do not like. The question itself is incredibly trivial, and fails to even outline the basic requirements. Answers there already start in the red there because they encourage these sorts of lazy questions. But a really clever answer that makes me think, "wow I never would have thought of that" could get out of the red even to an upvote by my metrics.
And the thing is, having read the answers, they are by in large not good. Some of them are in my opinion so lazy that they would warrant a downvote even if they were not already encouraging bad questions.
So why no comments?
I usually leave a comment when I think that there is something that I would change to make the thing I downvoted better. I don't really have suggestions for these answers. What I would like is for them to be more inventive or clever, or to not exist at all. In short I would like them to be less bad, which is to me what a downvote says on its own.
To me I feel that leaving comments that don't offer anything constructive can come off as vindictive or targeting. I really don't have a personal issue with anyone there, nor do I want to start any sort of argument.
Maybe I am wrong to think that I cannot be constructive here. Maybe you can help me be more constructive. If you know how I can do this then I am all ears.
You are of course free to disagree with me. I am fully aware what I say is good or bad is just my personal opinion. You might think that these answers are not bad. You are free to upvote them, I'd rather you not, I secretly like it when people agree with me, but you are free to do so.
