I've only now read about this issue (I'm not very active in the meta boards and Reputation) and don't want to add unnecessary content, but it's possible the forum has lost 1miau (they locked several threads with competitions and cancelled them, see
this,
this and
this one).
In my opinion it would be a very sad outcome if 1miau really left, and really hope they can calm down a bit, maybe take a time to relax and then come back, and their "adversaries" in this dispute think a bit about their actions as well. I think 1miau are an excellent high-quality post author and I support their activities against shitposting as well. However I agree with some of you that they may get easily into heated discussions and "shoot over the target" sometimes. And while I agree that everybody can handle their trust settings like they please, I think it should not be used to pressure others. However, some of 1miau's adversaries have shown
very questionable stances (radical right-wing in most cases) in some off-topic threads, so I can understand 1miau's anger a bit.
I always wonder when I see such meta problems deriving in such drama but whatever. Let's talk more about Bitcoin instead

It might be sad for you or people who enjoyed their posts, but it is definitely not sad for the users who have been attacked by 1miau, who have been dragged into days and days of battling with his drama is simply not rational discussion, or fair debate. 1miau will crop content of quotes so that he can respond inappropriately and confuse the reader, 1miau will abuse and insult and then complain when others retaliate, 1miau will add negative labels that apply more to them than to anyone else - and get away with it all.
Imagine how many good members have left because of his tirades, or how many have received negative labels that maybe they did not actually deserve?
Everyone is capable of being a high quality member...but a member who disrupts community participation is a member who will not be missed.
To address what you have said, I doubt 1miau is gone. I am sure they will do or say something soon.
