I think there used to be pages of angry posts before closing a 'serious discussion & debate' thread was considered. (Other than Voss sometimes closing a thread after a few off topic posts. But for as long as they were semi on topic..)
It used to be a last resort type of deal.
I don't remember mods ever editing posts either tbh.
Now a few angry posts and an entire thread is closed?
Go follow the site rules and give people infractions for not following the subforums or sites rules if you must, but please stop closing threads unless absolutely necessary?
