Could you be clearer about "a single noisy neighbor sending a bit too
much mail without jumping through the necessary hoops."

I've seen individual senders blocked for being new (it was pretty comical 
what MS did when I set up a 30 day test account at O365 last month) but I 
haven't seen that block an entire IP range.  Bot spam will do that.

> Is "filter responsibly" also off the table?

Depends how much you want to pay people to accept your mail.  I don't 
think we want to go there.
