Having no hosts, I can't do much about that other than use various  
good best practices (including BCP38), run ids units looking for  
compromised hosts, and respond quickly to each abuse report if my IDS  
doesn't observe it first.

Given that I know of no provider larger than us using BCP38 on every  
port, and no other provider larger than us that responds to every  
abuse report, it would appear that we are top of the class in that  

Therefore, when someone says "I don't need to do BCP38" because BCP38  
doesn't cause problems for them, I consider them a jerk.  And yeah, I  
feel pretty confident looking down my nose at someone like that.
