Staff do communicate on punishments they may question before they actually proceed with the action. There is a staff chat that is private in the game where staff members communicate on punishments, event coordination, etc. But I do agree how each staff member have their own way of handling a situation and how they can interpret things too bluntly as you describe it. Some staff members who are too blunt with the situation will communicate and some others will proceed to do their own thing. In the punishment guidelines (I have no clue if they have actually updated it) inappropriate behavior is not warned and just given directly as a 5 hour long punishment. If you had staff members warn you about inappropriate behavior they are being lenient about it.
All I consider doing is to DM one of the staff members on Discord if you are so curious and ask them why you have been muted for the context you said which they thought would be redeemed as "inappropriate." Just be aware that if you are lucky enough they might provide an explanation. If not, they are just going to redirect you to appealing which I don't recommend at all since it's wasted effort. But hey, you do you.
