How would you write a program to process error messages and decide which user 
accounts to disable?

As to blocking repeated login failures, there are such things. I wrote one 
myself and have it running on my Linux box (the DragonFly box is a laptop and 
isn't publicly visible). It doesn't care whether the source of the logins is 
in China or my net-door neighbor (or even the laptop, which looks like the 
router's external IP the way it's forwarded).
