I don't care to know exactly who closes a thread, but the reason why is important. Hopefully, any moderator that is closing a thread is at least telling the offending posters why. I haven't seen it lately, but in the past there have been public warnings issued. Cutting off valid discussions by closing a thread is much worse than dealing with individual poor postings.
I also hate when someone deletes one of your post with not warning/explanation. It's confusing. It took me a bit to realize that a moderator made a very poor post which I called them out on. They deleted my post as well as their own.
At least this forum is better than most. I had one which would not allow any post which even questioned the "arrival of unicorns" (won't disclose the topic). I was attacked for asking some questions and stating concerns I had. Then the OP said I had a bad tone. He wouldn't point to a single post or line in a post as to what I was saying wrong. I realized that the forum wasn't around the "arrival of unicorns", but the full cheering of those drinking the Koolaid.
