What should I do if mods declined a flag I think was legitimate and regard violation of the code of conduct?

Question

There's a user who's been posting pointless, off topic comments where I post genuine questions.

Yesterday they chose to necropost on a 3 years and 4 months old question of mine, in a clear attempt to start a comments war over something that had nothing to do with what I asked proper. They also acted unfriendly and out of the blue began flaming at the comments. To me they seemed like infringing the code of conduct in several ways, so I flagged all of their comments and they all got removed.

At around the same time they came to my newly asked question, specifically, a word request: What's the word for someone who takes a conceited stance in stead of their bosses in order to appear important?

Although in a milder tone, the attitude here seems the same: trying to discredit whatever I gave as an example and trying to drag me into an argument. It started with a comment on my question, then an answer. As I ignored them, another comment along the same lines on their own answer, then another, then another.

I flagged their answer as not being an answer and it was not removed.

I think it should be, since for 2 reasons I see it clear that it's not an answer to my question and was never meant to be, namely:

1. They altogether avoided the central point of my question, clearly trying to discredit the situation I used as an illustration rather than trying to provide a solution to my doubt.
2. They clearly write as if attempting provocation, intent on me answering/getting angry so as to start a fight

You mods may not see it like that, but that's exactly how they started a war at my other question's comment section.

I personally think SE is not a place for such attitudes, but rather a curated knowledge repository. Just check my other profiles on the network and see I only come here with genuine questions that, if answered, I earnestly think will produce genuine knowledge.

These stupid quarrels and off-topic provocations belong in Reddit, not here. Allowing people, especially an older and supposedly experienced user to keep going on posting such, not only encourages their behaviour but overall contributes to a decrease in standards within the community.

Besides, I feel it's not just to keep that on, i've been called out for much less on SE and in my eyes this answer clearly violated the code of conduct, no so much by it's content (which is irrelevant anyways, as it does not answer the question), but by tone and intent expressed. Namely, starting a quarrel.

Answer 1

To answer the immediate issue, I declined your Not An Answer flag because I judged there was no evidence to support that conclusion. The answer is an answer. It's OK for an answer to challenge the premise of the question, or to answer part of it. See the MSE posts on this flag.

You may not like the answer. That's fine; you don't have to accept that one. You can even downvote it.

I might be wrong, and raising a Meta post is fine. Another moderator will take another look, although there may be timezones to consider. It's possible the answer will be removed; it's possible it won't be.

You are quite right that Stack Exchange is not a place for quarrels. The first rule of apparently being targeted is If you feel you're being goaded, don't rise to it. However, moderators will look into all reports of bad behaviour, including here. You may not see what actions are or are not taken: we don't make interactions between moderators and users public — except where a user raises a concern, as you have here, in which case our interaction with you needs to be made public to answer the concern; or where the result is a suspension (and even then, the reason given for suspension is couched in rather general terms).

As has been said in the comments, Real Life has to take precedence; and in interactions between users and within the moderator team (yes, we do use chat to talk to each other), timezones also come into play.
