[members-discuss] **SPAM** Re: Technical solution to resolve Spoofed IP traffic, Spoofed amplification DDoS attacks, BGP&RIR hijacking, IoT botnet infections and Botnet C&Cs

Hi!


What about the internet traffic in doubling every packet and the 
electrical power to do the cryptographic operations? Or do you want to 
make every router in the world stateful?


As much as I would love to see you elected and make a complete fool of 
yourself, I can not risk the reputation of RIPE... At the moment I do 
not fancy any candidate, nor do I support one.
