Let's be savvy. That is the best option for everybody. It is just funny to notice that it is always the same people that will suffer from spam and it will always create profits for others, not only spammers, but also people that can sell products and services to fight against - think of the millions Postini, MXLogic, Messagelabs, Ironport, Websense and all other AV/AS/App. solutions made out of that.

That is why I started  http://scavenger.exa.org.uk/ used with BGP FlowSpec to redirect traffic it should spam nicely http://bgp.exa.org.uk/
It is just a pity, I do not much time to work on the code atm, but will surely later on this year.
