So there might be some context I missed but this is what I saw:
A user made a post about a month ago where they suggested changes related to moderation. I didn't agree with all their suggestions but still they made some valid points especially about transparency and I didn't see anything wrong with the post.
For example I remember one mentioned issue was, that the moderation log is public but doesn't provide enough context about the severity of the offense.
I was actually writing a reply then agreeing with some points and providing related suggestions of my own. For example I was trying to suggest a "severity level" displayed in the public moderation log because obviously not all offenses are equal. Like if a user who said something mildly offensive let's say "shuri so gay" may feel bad when the public log just shows "Abuse on the grounds of sexual orientation". A "severity: minor offense" would help provide context and maybe would help the next time a moderator sees that user reported to not assume the worst, hence reducing the chance of over-moderation.
But the thread was locked before I could post my reply. The reason for the lock and the user's mute was just a screenshot they shared where a moderator confirmed them the reason for a 5 day suspension was the comment "shuri so gay".
Today I saw the same user's new post about "clarification on the moderation policy" where again I didn't see anything wrong, they were just wanted to know for example what to do if there are wind turbines in the way of their units while there's a rule to not grief allies by destroying their buildings.
I can only report what I saw: moderator comes in and says the user was warned. User seconds later (probably couldn't even read that warning) writes in all caps something like "shut up" (not exact quote, I can't see the post anymore), then the moderator bans them I assume permanently then locked and removed the thread.
