Come to think of it, there are probably botnets for rent where the
"owner" has verified non-compliance with BCP38 and will arrange for X
number of fresh machines spread across everywhere to VPN into your
server and pass packets for you. Why not bring in a little extra cash
while waiting for the next DDOS target? Particularly when the packets
emitted are unlikely to be traceable to the bot.
