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.
