This is no POC, we have seen this happen many many times. Perhaps some 
drone networks are a little 'behind' but in general, they are perfectly 
able to do this. Even with some static lists for some large ISPs 
mailservers they can perfectly initiate it large scale. And yes, it does 
limit, but with the number of bots we see controlled on the few botnets we 
monitored the impact will still be hudge.
