How can we convince the Moderators to do their job of cleaning the low-quality content?

Question

During the course of recent months, we've had discussions on the dichotomy between poorly written, low-quality content and welcoming new users who often post such content.

Today, one post strikes me. It has only a single thought within; its author is criticizing another answer on using термінУ versus термінА. No attempt to answer the question has been done. The original question was about reflexive verbs.

Our brilliant diamond Moderator has warmly welcomed the poster and… left it alone, probably hoping that the user has something to say someday in this post. Here's the comment written by the Mod:

Миколо, дуже дякуємо! Ми виправили текст. Однак, на майбутнє: такі зауваження краще або оформлювати в коментарях (натискаючи «add a comment» — щоправда Ви поки не маєте права писати коментарі), або напряму пропонувати виправлення (натискаючи «improve this answer» чи «improve this question» — це найкращий спосіб). Адже кнопка для відповіді («Post Your Answer») призначена для введення, власне, відповіді на запитання. Але все одно дякуємо!

Putting aside problems of "when to delete a half-baked content", this post is not half-baked.
It it totally useless as an answer and must be deleted.
Its content might be a source for edit in the original question (a single character, yes), but it does not count as answer at all.

In a healthy user community, this post would quickly collect its deserved down- and delete- votes and would be happily deleted over a couple of hours. Our community, however, is extremely passive, so the role of diamond Moderators is growing higher than on sister SE sites.

This is not the first case of such neglect of their responsibilities, and I think the Users' Community should say our word.

Question: How can we, as the Ukrainian.SE user community, convince our diamond Moderators act accordingly to the rules of Stack Exchange system? If you find this question too broad because the Mods have multiple responsibilities, let us focus on a single one:

Removing non-answers, e.g. posts that only criticize the question or another answer, but written by pressing "Post the Answer" button

Answer 1

• On the one hand, I agree that such “answers” must not exist on the site.
• On the other hand, we should be welcoming to people.

So, my decision was to remove that “answer”, but to do it not immediately (first, immediate removal of the post may make a newcomer to feel uncomfortable per se, second, if a newcomer's post is immediately removed, they are unable to express objections and/or ask for clarifications (as a newcomer is able to comment only his own post; so he might be in a gridlock: having neither enough experience to write questions/answer nor enough reputation to participate in comments/meta)).

Maybe I am wrong, but that's what I would do in case of such well-intentioned mis-uses: (1) write a truly-welcoming comment that tries to correct the newcomer's behavior; (2) give the visitor a chance to reply the comment; (3) delete the post.
