From Newsgroup: news.admin.moderation
"A natural response to the examples of detailed correspondence
provided to problem users that have a history of rejected submissions
to moderated newsgroups (examples that were just posted to this
subreddit), is why go to all of this trouble? Why not just ban them,
or even pre-emptively ban them, and without detailed explanation? Most
of the time, these users won't take feedback, even constructive
feedback provided privately, and may choose to argue in public about
it."
