As I see it, the last few pages of this thread have simply turned into a personal squabble and settling of scores.

I agree, a dialogue, as I already said, did not work out. Therefore, the discussion of this issue is closed. I didn't create the rules, and it's not within my competence to change them.

A small suggestion - make it so that it is always visible for any topic - what can be written in it. Either give explanations in the topic title, or (as is done in Tournaments) - so that every (not just the first) page of the topic always starts with an explanation - what the topic is for, and what can and cannot be written in it....

When creating a topic, you can choose one of the existing titles (Tournament, Discussion, Problem, Question, etc.), or create your own, no one prevents this. The title of the topic itself should also contain the main goal, problem, or idea. Just like the first post should be as informative as possible. The first post can be pinned (as is done in tournament topics), then it will be visible on every new page. But if for tournaments this is more of a mandatory condition (it is still more convenient to open the last page and have the opportunity to see the rules, the table of participants on it, and not scroll to the first page - this saves time, traffic, and nerves, especially for the organizers, who have to edit the first post several times, adding participants to the table, etc.), then for other topics it is not at all mandatory. Currently, this function is disabled, probably due to the load on the forum (due to which some functions are disabled), but I cannot say for sure, I do not have such information.
To know what can be written and what cannot, there are rules that ideally all users should read upon registration. But nothing prevents the author of the topic, when creating it, from writing about what he wants to see in his topic, and what is strictly not allowed. Although, in general, everyone should understand that it is necessary to write within the scope of this topic.
This is exactly what moderators are for, whose responsibility is to monitor order in their assigned section. And the authors of topics need to create their topics competently. No one can force anyone to do this, so we can only hope for the conscientiousness of users.

And the second suggestion....

There are 2 types of post deletion: soft and physical. Only coordinators, and of course the administrator, can physically delete posts. Moderators do not have the authority to delete posts in this way; they delete posts softly. That is, the post becomes unreadable for users, but the moderator can view this post at any time, as well as restore it if it is proven that the post was deleted unlawfully. If a user disagrees with the moderator's decision, he can complain to the coordinator. The coordinator can read soft-deleted posts in any section, as well as restore them if necessary!
This is why moderators do not have the ability to physically delete posts. Thus, the post does not disappear anywhere; it is simply hidden from view by users.

and moving messages, if I'm not mistaken, is not allowed for everyone.

A moderator has the ability to move messages or topics to any other topic or sub-section, but only if that topic, section, or sub-section is within their authority. For example, a moderator of the Heroes 5 section cannot move topics or messages to the Heroes 3 section.
